- * The libFLAC++ decoder classes are object wrappers around their
- * counterparts in libFLAC.  All decoding layers available in
- * libFLAC are also provided here.  The interface is very similar;
- * make sure to read the \link flac_decoder libFLAC decoder module \endlink.
- *
- * There are only two significant differences here.  First, instead of
- * passing in C function pointers for callbacks, you inherit from the
- * decoder class and provide implementations for the callbacks in your
- * derived class; because of this there is no need for a 'client_data'
- * property.
- *
- * Second, there are two stream decoder classes.  FLAC::Decoder::Stream
- * is used for the same cases that FLAC__stream_decoder_init_stream() /
- * FLAC__stream_decoder_init_ogg_stream() are used, and FLAC::Decoder::File
- * is used for the same cases that
- * FLAC__stream_decoder_init_FILE() and FLAC__stream_decoder_init_file() /
- * FLAC__stream_decoder_init_ogg_FILE() and FLAC__stream_decoder_init_ogg_file()
- * are used.

-		 *
-		 * The usage of this class is similar to FLAC__StreamDecoder,
-		 * except instead of providing callbacks to
-		 * FLAC__stream_decoder_init*_stream(), you will inherit from this
-		 * class and override the virtual callback functions with your
-		 * own implementations, then call init() or init_ogg().  The rest
-		 * of the calls work the same as in the C layer.
-		 *
-		 * Only the read, write, and error callbacks are mandatory.  The
-		 * others are optional; this class provides default
-		 * implementations that do nothing.  In order for seeking to work
-		 * you must overide seek_callback(), tell_callback(),

- *  This module describes the encoder layers provided by libFLAC++.
- *
- * The libFLAC++ encoder classes are object wrappers around their
- * counterparts in libFLAC.  All encoding layers available in
- * libFLAC are also provided here.  The interface is very similar;
- * make sure to read the \link flac_encoder libFLAC encoder module \endlink.
- *
- * There are only two significant differences here.  First, instead of
- * passing in C function pointers for callbacks, you inherit from the
- * encoder class and provide implementations for the callbacks in your
- * derived class; because of this there is no need for a 'client_data'
- * property.
- *
- * Second, there are two stream encoder classes.  FLAC::Encoder::Stream
- * is used for the same cases that FLAC__stream_encoder_init_stream() /
- * FLAC__stream_encoder_init_ogg_stream() are used, and FLAC::Encoder::File
- * is used for the same cases that
- * FLAC__stream_encoder_init_FILE() and FLAC__stream_encoder_init_file() /
- * FLAC__stream_encoder_init_ogg_FILE() and FLAC__stream_encoder_init_ogg_file()
- * are used.

-		 *
-		 *  \brief
-		 *  Level 2 metadata iterator.
-		 *
-		 *  The flow through the iterator in the C++ layer is similar
-		 *  to the C layer:
-		 *    - Create a Chain instance
-		 *    - Check Chain::is_valid()
-		 *    - Call Chain::read() and check the return
-		 *    - Traverse and/or edit with an Iterator or with
-		 *      Chain::merge_padding() or Chain::sort_padding()
-		 *    - Write changes back to FLAC file with Chain::write()
-		 *    - Destroy the Chain instance
-		 *
-		 *  The ownership of pointers in the C++ layer is slightly
-		 *  different than in the C layer, i.e.
-		 *    - The objects returned by Iterator::get_block() are NOT
-		 *      owned by the iterator and should be deleted by the
-		 *      caller when finished, BUT, when you modify the block,
-		 *      it will directly edit what's in the chain and you do
-		 *      not need to call Iterator::set_block().  However the
-		 *      changes will not be reflected in the FLAC file until
-		 *      the chain is written with Chain::write().
-		 *    - When you pass an object to Iterator::set_block(),
-		 *      Iterator::insert_block_before(), or
-		 *      Iterator::insert_block_after(), the iterator takes
-		 *      ownership of the block and it will be deleted by the
-		 *      chain.
-		 *
-		 *  See the \link flac_metadata_level2 C layer equivalent \endlink
-		 *  for more.

-/** \mainpage
- *
- * \section intro Introduction
- *
- * This is the documentation for the FLAC C and C++ APIs.  It is
- * highly interconnected; this introduction should give you a top
- * level idea of the structure and how to find the information you
- * need.  As a prerequisite you should have at least a basic
- * knowledge of the FLAC format, documented
- * <A HREF="../format.html">here</A>.
- *
- * \section c_api FLAC C API
- *
- * The FLAC C API is the interface to libFLAC, a set of structures
- * describing the components of FLAC streams, and functions for
- * encoding and decoding streams, as well as manipulating FLAC
- * metadata in files.  The public include files will be installed
- * in your include area (for example /usr/include/FLAC/...).
- *
- * By writing a little code and linking against libFLAC, it is
- * relatively easy to add FLAC support to another program.  The
- * library is licensed under <A HREF="../license.html">Xiph's BSD license</A>.
- * Complete source code of libFLAC as well as the command-line
- * encoder and plugins is available and is a useful source of
- * examples.
- *
- * Aside from encoders and decoders, libFLAC provides a powerful
- * metadata interface for manipulating metadata in FLAC files.  It
- * allows the user to add, delete, and modify FLAC metadata blocks
- * and it can automatically take advantage of PADDING blocks to avoid
- * rewriting the entire FLAC file when changing the size of the
- * metadata.
- *
- * libFLAC usually only requires the standard C library and C math
- * library. In particular, threading is not used so there is no
- * dependency on a thread library. However, libFLAC does not use
- * global variables and should be thread-safe.
- *
- * libFLAC also supports encoding to and decoding from Ogg FLAC.
- * However the metadata editing interfaces currently have limited
- * read-only support for Ogg FLAC files.
- *
- * \section cpp_api FLAC C++ API
- *
- * The FLAC C++ API is a set of classes that encapsulate the
- * structures and functions in libFLAC.  They provide slightly more
- * functionality with respect to metadata but are otherwise
- * equivalent.  For the most part, they share the same usage as
- * their counterparts in libFLAC, and the FLAC C API documentation
- * can be used as a supplement.  The public include files
- * for the C++ API will be installed in your include area (for
- * example /usr/include/FLAC++/...).
- *
- * libFLAC++ is also licensed under
- * <A HREF="../license.html">Xiph's BSD license</A>.
- *
- * \section getting_started Getting Started
- *
- * A good starting point for learning the API is to browse through
- * the <A HREF="modules.html">modules</A>.  Modules are logical
- * groupings of related functions or classes, which correspond roughly
- * to header files or sections of header files.  Each module includes a
- * detailed description of the general usage of its functions or
- * classes.
- *
- * From there you can go on to look at the documentation of
- * individual functions.  You can see different views of the individual
- * functions through the links in top bar across this page.
- *
- * If you prefer a more hands-on approach, you can jump right to some
- * <A HREF="../documentation_example_code.html">example code</A>.
- *
- * \section porting_guide Porting Guide
- *
- * Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink
- * has been introduced which gives detailed instructions on how to
- * port your code to newer versions of FLAC.
- *
- * \section embedded_developers Embedded Developers
- *
- * libFLAC has grown larger over time as more functionality has been
- * included, but much of it may be unnecessary for a particular embedded
- * implementation.  Unused parts may be pruned by some simple editing of
- * src/libFLAC/Makefile.am.  In general, the decoders, encoders, and
- * metadata interface are all independent from each other.
- *
- * It is easiest to just describe the dependencies:
- *
- * - All modules depend on the \link flac_format Format \endlink module.
- * - The decoders and encoders depend on the bitbuffer.
- * - The decoder is independent of the encoder.  The encoder uses the
- *   decoder because of the verify feature, but this can be removed if
- *   not needed.
- * - Parts of the metadata interface require the stream decoder (but not
- *   the encoder).
- * - Ogg support is selectable through the compile time macro
- *   \c FLAC__HAS_OGG.
- *
- * For example, if your application only requires the stream decoder, no
- * encoder, and no metadata interface, you can remove the stream encoder
- * and the metadata interface, which will greatly reduce the size of the
- * library.
- *
- * Also, there are several places in the libFLAC code with comments marked
- * with "OPT:" where a #define can be changed to enable code that might be
- * faster on a specific platform.  Experimenting with these can yield faster
- * binaries.
- */
-
-/** \defgroup porting Porting Guide for New Versions
- *
- * This module describes differences in the library interfaces from
- * version to version.  It assists in the porting of code that uses
- * the libraries to newer versions of FLAC.
- *
- * One simple facility for making porting easier that has been added
- * in FLAC 1.1.3 is a set of \c #defines in \c export.h of each
- * library's includes (e.g. \c include/FLAC/export.h).  The
- * \c #defines mirror the libraries'
- * <A HREF="http://www.gnu.org/software/libtool/manual/libtool.html#Libtool-versioning">libtool version numbers</A>,
- * e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT,
- * \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE.
- * These can be used to support multiple versions of an API during the
- * transition phase, e.g.
- *
- * \code
- * #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7
- *   legacy code
- * #else
- *   new code
- * #endif
- * \endcode
- *
- * The source will work for multiple versions and the legacy code can
- * easily be removed when the transition is complete.
- *
- * Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in
- * include/FLAC/export.h), which can be used to determine whether or not
- * the library has been compiled with support for Ogg FLAC.  This is
- * simpler than trying to call an Ogg init function and catching the
- * error.

-/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3
- *  \ingroup porting
- *
- *  \brief
- *  This module describes porting from FLAC 1.1.2 to FLAC 1.1.3.
- *
- * The main change between the APIs in 1.1.2 and 1.1.3 is that they have
- * been simplified.  First, libOggFLAC has been merged into libFLAC and
- * libOggFLAC++ has been merged into libFLAC++.  Second, both the three
- * decoding layers and three encoding layers have been merged into a
- * single stream decoder and stream encoder.  That is, the functionality
- * of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged
- * into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and
- * FLAC__FileEncoder into FLAC__StreamEncoder.  Only the
- * FLAC__StreamDecoder and FLAC__StreamEncoder remain.  What this means
- * is there is now a single API that can be used to encode or decode
- * streams to/from native FLAC or Ogg FLAC and the single API can work
- * on both seekable and non-seekable streams.
- *
- * Instead of creating an encoder or decoder of a certain layer, now the
- * client will always create a FLAC__StreamEncoder or
- * FLAC__StreamDecoder.  The old layers are now differentiated by the
- * initialization function.  For example, for the decoder,
- * FLAC__stream_decoder_init() has been replaced by
- * FLAC__stream_decoder_init_stream().  This init function takes
- * callbacks for the I/O, and the seeking callbacks are optional.  This
- * allows the client to use the same object for seekable and
- * non-seekable streams.  For decoding a FLAC file directly, the client
- * can use FLAC__stream_decoder_init_file() and pass just a filename
- * and fewer callbacks; most of the other callbacks are supplied
- * internally.  For situations where fopen()ing by filename is not
- * possible (e.g. Unicode filenames on Windows) the client can instead
- * open the file itself and supply the FILE* to
- * FLAC__stream_decoder_init_FILE().  The init functions now returns a
- * FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState.
- * Since the callbacks and client data are now passed to the init
- * function, the FLAC__stream_decoder_set_*_callback() functions and
- * FLAC__stream_decoder_set_client_data() are no longer needed.  The
- * rest of the calls to the decoder are the same as before.
- *
- * There are counterpart init functions for Ogg FLAC, e.g.
- * FLAC__stream_decoder_init_ogg_stream().  All the rest of the calls
- * and callbacks are the same as for native FLAC.
- *
- * As an example, in FLAC 1.1.2 a seekable stream decoder would have
- * been set up like so:
- *
- * \code
- * FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new();
- * if(decoder == NULL) do_something;
- * FLAC__seekable_stream_decoder_set_md5_checking(decoder, true);
- * [... other settings ...]
- * FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback);
- * FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback);
- * FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback);
- * FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback);
- * FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback);
- * FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback);

- * if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something;
- * \endcode
- *
- * In FLAC 1.1.3 it is like this:
- *
- * \code
- * FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new();
- * if(decoder == NULL) do_something;
- * FLAC__stream_decoder_set_md5_checking(decoder, true);

- *   my_seek_callback,      // or NULL
- *   my_tell_callback,      // or NULL
- *   my_length_callback,    // or NULL
- *   my_eof_callback,       // or NULL
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * or you could do;
- *
- * \code
- * [...]
- * FILE *file = fopen("somefile.flac","rb");
- * if(file == NULL) do_somthing;
- * if(FLAC__stream_decoder_init_FILE(
- *   decoder,
- *   file,
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * or just:
- *
- * \code
- * [...]
- * if(FLAC__stream_decoder_init_file(
- *   decoder,
- *   "somefile.flac",
- *   my_write_callback,
- *   my_metadata_callback,  // or NULL
- *   my_error_callback,
- *   my_client_data
- * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something;
- * \endcode
- *
- * Another small change to the decoder is in how it handles unparseable
- * streams.  Before, when the decoder found an unparseable stream
- * (reserved for when the decoder encounters a stream from a future
- * encoder that it can't parse), it changed the state to
- * \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM.  Now the decoder instead
- * drops sync and calls the error callback with a new error code
- * \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM.  This is
- * more robust.  If your error callback does not discriminate on the the
- * error state, your code does not need to be changed.
- *
- * The encoder now has a new setting:
- * FLAC__stream_encoder_set_apodization().  This is for setting the
- * method used to window the data before LPC analysis.  You only need to
- * add a call to this function if the default is not suitable.   There
- * are also two new convenience functions that may be useful:
- * FLAC__metadata_object_cuesheet_calculate_cddb_id() and
- * FLAC__metadata_get_cuesheet().
- *
- * The \a bytes parameter to FLAC__StreamDecoderReadCallback,
- * FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback
- * is now \c size_t instead of \c unsigned.

- *
- *  \brief
- *  This module defines the structures for describing I/O callbacks
- *  to the other FLAC interfaces.
- *
- *  The purpose of the I/O callback functions is to create a common way
- *  for the metadata interfaces to handle I/O.
- *
- *  Originally the metadata interfaces required filenames as the way of
- *  specifying FLAC files to operate on.  This is problematic in some
- *  environments so there is an additional option to specify a set of
- *  callbacks for doing I/O on the FLAC file, instead of the filename.
- *
- *  In addition to the callbacks, a FLAC__IOHandle type is defined as an
- *  opaque structure for a data source.
- *
- *  The callback function prototypes are similar (but not identical) to the
- *  stdio functions fread, fwrite, fseek, ftell, feof, and fclose.  If you use
- *  stdio streams to implement the callbacks, you can pass fread, fwrite, and
- *  fclose anywhere a FLAC__IOCallback_Read, FLAC__IOCallback_Write, or
- *  FLAC__IOCallback_Close is required, and a FILE* anywhere a FLAC__IOHandle
- *  is required.  \warning You generally CANNOT directly use fseek or ftell
- *  for FLAC__IOCallback_Seek or FLAC__IOCallback_Tell since on most systems
- *  these use 32-bit offsets and FLAC requires 64-bit offsets to deal with
- *  large files.  You will have to find an equivalent function (e.g. ftello),
- *  or write a wrapper.  The same is true for feof() since this is usually
- *  implemented as a macro, not as a function whose address can be taken.

- *  First, you should be familiar with the

- *
- *  The format structures here are very primitive, designed to store
- *  information in an efficient way.  Reading information from the
- *  structures is easy but creating or modifying them directly is
- *  more complex.  For the most part, as a user of a library, editing
- *  is not necessary; however, for metadata blocks it is, so there are
- *  convenience functions provided in the \link flac_metadata metadata
- *  module \endlink to simplify the manipulation of metadata blocks.
- *
- * \note
- * It's not the best convention, but symbols ending in _LEN are in bits
- * and _LENGTH are in bytes.  _LENGTH symbols are \#defines instead of
- * global variables because they are usually used when declaring byte
- * arrays and some compilers require compile-time knowledge of array
- * sizes when declared on the stack.

- *  \ingroup flac
- *
- *  \brief
- *  This module provides functions for creating and manipulating FLAC
- *  metadata blocks in memory, and three progressively more powerful
- *  interfaces for traversing and editing metadata in native FLAC files.
- *  Note that currently only the Chain interface (level 2) supports Ogg
- *  FLAC files, and it is read-only i.e. no writing back changed
- *  metadata to file.
- *
- *  There are three metadata interfaces of increasing complexity:
- *
- *  Level 0:
- *  Read-only access to the STREAMINFO, VORBIS_COMMENT, CUESHEET, and
- *  PICTURE blocks.
- *
- *  Level 1:
- *  Read-write access to all metadata blocks.  This level is write-
- *  efficient in most cases (more on this below), and uses less memory
- *  than level 2.
- *
- *  Level 2:
- *  Read-write access to all metadata blocks.  This level is write-
- *  efficient in all cases, but uses more memory since all metadata for
- *  the whole file is read into memory and manipulated before writing
- *  out again.
- *
- *  What do we mean by efficient?  Since FLAC metadata appears at the
- *  beginning of the file, when writing metadata back to a FLAC file
- *  it is possible to grow or shrink the metadata such that the entire
- *  file must be rewritten.  However, if the size remains the same during
- *  changes or PADDING blocks are utilized, only the metadata needs to be
- *  overwritten, which is much faster.
- *
- *  Efficient means the whole file is rewritten at most one time, and only
- *  when necessary.  Level 1 is not efficient only in the case that you
- *  cause more than one metadata block to grow or shrink beyond what can
- *  be accomodated by padding.  In this case you should probably use level
- *  2, which allows you to edit all the metadata for a file in memory and
- *  write it out all at once.
- *
- *  All levels know how to skip over and not disturb an ID3v2 tag at the
- *  front of the file.
- *
- *  All levels access files via their filenames.  In addition, level 2
- *  has additional alternative read and write functions that take an I/O
- *  handle and callbacks, for situations where access by filename is not
- *  possible.
- *
- *  In addition to the three interfaces, this module defines functions for
- *  creating and manipulating various metadata objects in memory.  As we see
- *  from the Format module, FLAC metadata blocks in memory are very primitive
- *  structures for storing information in an efficient way.  Reading
- *  information from the structures is easy but creating or modifying them
- *  directly is more complex.  The metadata object routines here facilitate
- *  this by taking care of the consistency and memory management drudgery.
- *
- *  Unless you will be using the level 1 or 2 interfaces to modify existing
- *  metadata however, you will not probably not need these.
- *
- *  From a dependency standpoint, none of the encoders or decoders require
- *  the metadata module.  This is so that embedded users can strip out the
- *  metadata module from libFLAC to reduce the size and complexity.

- *  \ingroup flac_metadata
- *
- * \brief
- * The level 1 interface provides read-write access to FLAC file metadata and
- * operates directly on the FLAC file.
- *
- * The general usage of this interface is:
- *
- * - Create an iterator using FLAC__metadata_simple_iterator_new()
- * - Attach it to a file using FLAC__metadata_simple_iterator_init() and check
- *   the exit code.  Call FLAC__metadata_simple_iterator_is_writable() to
- *   see if the file is writable, or only read access is allowed.
- * - Use FLAC__metadata_simple_iterator_next() and
- *   FLAC__metadata_simple_iterator_prev() to traverse the blocks.
- *   This is does not read the actual blocks themselves.
- *   FLAC__metadata_simple_iterator_next() is relatively fast.
- *   FLAC__metadata_simple_iterator_prev() is slower since it needs to search
- *   forward from the front of the file.
- * - Use FLAC__metadata_simple_iterator_get_block_type() or
- *   FLAC__metadata_simple_iterator_get_block() to access the actual data at
- *   the current iterator position.  The returned object is yours to modify
- *   and free.
- * - Use FLAC__metadata_simple_iterator_set_block() to write a modified block
- *   back.  You must have write permission to the original file.  Make sure to
- *   read the whole comment to FLAC__metadata_simple_iterator_set_block()
- *   below.
- * - Use FLAC__metadata_simple_iterator_insert_block_after() to add new blocks.
- *   Use the object creation functions from
- *   \link flac_metadata_object here \endlink to generate new objects.
- * - Use FLAC__metadata_simple_iterator_delete_block() to remove the block
- *   currently referred to by the iterator, or replace it with padding.
- * - Destroy the iterator with FLAC__metadata_simple_iterator_delete() when
- *   finished.
- *
- * \note
- * The FLAC file remains open the whole time between
- * FLAC__metadata_simple_iterator_init() and
- * FLAC__metadata_simple_iterator_delete(), so make sure you are not altering
- * the file during this time.
- *
- * \note
- * Do not modify the \a is_last, \a length, or \a type fields of returned
- * FLAC__StreamMetadata objects.  These are managed automatically.
- *
- * \note
- * If any of the modification functions
- * (FLAC__metadata_simple_iterator_set_block(),
- * FLAC__metadata_simple_iterator_delete_block(),
- * FLAC__metadata_simple_iterator_insert_block_after(), etc.) return \c false,
- * you should delete the iterator as it may no longer be valid.

- *  \ingroup flac_metadata
- *
- * \brief
- * The level 2 interface provides read-write access to FLAC file metadata;
- * all metadata is read into memory, operated on in memory, and then written
- * to file, which is more efficient than level 1 when editing multiple blocks.
- *
- * Currently Ogg FLAC is supported for read only, via
- * FLAC__metadata_chain_read_ogg() but a subsequent
- * FLAC__metadata_chain_write() will fail.
- *
- * The general usage of this interface is:
- *
- * - Create a new chain using FLAC__metadata_chain_new().  A chain is a
- *   linked list of FLAC metadata blocks.
- * - Read all metadata into the chain from a FLAC file using
- *   FLAC__metadata_chain_read() or FLAC__metadata_chain_read_ogg() and
- *   check the status.
- * - Optionally, consolidate the padding using
- *   FLAC__metadata_chain_merge_padding() or
- *   FLAC__metadata_chain_sort_padding().
- * - Create a new iterator using FLAC__metadata_iterator_new()
- * - Initialize the iterator to point to the first element in the chain
- *   using FLAC__metadata_iterator_init()
- * - Traverse the chain using FLAC__metadata_iterator_next and
- *   FLAC__metadata_iterator_prev().
- * - Get a block for reading or modification using
- *   FLAC__metadata_iterator_get_block().  The pointer to the object
- *   inside the chain is returned, so the block is yours to modify.
- *   Changes will be reflected in the FLAC file when you write the
- *   chain.  You can also add and delete blocks (see functions below).
- * - When done, write out the chain using FLAC__metadata_chain_write().
- *   Make sure to read the whole comment to the function below.
- * - Delete the chain using FLAC__metadata_chain_delete().
- *
- * \note
- * Even though the FLAC file is not open while the chain is being
- * manipulated, you must not alter the file externally during
- * this time.  The chain assumes the FLAC file will not change
- * between the time of FLAC__metadata_chain_read()/FLAC__metadata_chain_read_ogg()
- * and FLAC__metadata_chain_write().
- *
- * \note
- * Do not modify the is_last, length, or type fields of returned
- * FLAC__StreamMetadata objects.  These are managed automatically.
- *
- * \note
- * The metadata objects returned by FLAC__metadata_iterator_get_block()
- * are owned by the chain; do not FLAC__metadata_object_delete() them.
- * In the same way, blocks passed to FLAC__metadata_iterator_set_block()
- * become owned by the chain and they will be deleted when the chain is

-/** \defgroup flac_metadata_object FLAC/metadata.h: metadata object methods
- *  \ingroup flac_metadata
- *
- * \brief
- * This module contains methods for manipulating FLAC metadata objects.
- *
- * Since many are variable length we have to be careful about the memory
- * management.  We decree that all pointers to data in the object are
- * owned by the object and memory-managed by the object.
- *
- * Use the FLAC__metadata_object_new() and FLAC__metadata_object_delete()
- * functions to create all instances.  When using the
- * FLAC__metadata_object_set_*() functions to set pointers to data, set
- * \a copy to \c true to have the function make it's own copy of the data, or
- * to \c false to give the object ownership of your data.  In the latter case
- * your pointer must be freeable by free() and will be free()d when the object
- * is FLAC__metadata_object_delete()d.  It is legal to pass a null pointer as
- * the data pointer to a FLAC__metadata_object_set_*() function as long as
- * the length argument is 0 and the \a copy argument is \c false.
- *
- * The FLAC__metadata_object_new() and FLAC__metadata_object_clone() function
- * will return \c NULL in the case of a memory allocation error, otherwise a new
- * object.  The FLAC__metadata_object_set_*() functions return \c false in the
- * case of a memory allocation error.
- *
- * We don't have the convenience of C++ here, so note that the library relies
- * on you to keep the types straight.  In other words, if you pass, for
- * example, a FLAC__StreamMetadata* that represents a STREAMINFO block to
- * FLAC__metadata_object_application_set_data(), you will get an assertion
- * failure.
- *
- * For convenience the FLAC__metadata_object_vorbiscomment_*() functions
- * maintain a trailing NUL on each Vorbis comment entry.  This is not counted
- * toward the length or stored in the stream, but it can make working with plain
- * comments (those that don't contain embedded-NULs in the value) easier.
- * Entries passed into these functions have trailing NULs added if missing, and
- * returned entries are guaranteed to have a trailing NUL.
- *
- * The FLAC__metadata_object_vorbiscomment_*() functions that take a Vorbis
- * comment entry/name/value will first validate that it complies with the Vorbis
- * comment specification and return false if it does not.
- *
- * There is no need to recalculate the length field on metadata blocks you
- * have modified.  They will be calculated automatically before they  are
- * written back to a file.

- *
- * The stream decoder can be used to decode complete streams either from
- * the client via callbacks, or directly from a file, depending on how
- * it is initialized.  When decoding via callbacks, the client provides
- * callbacks for reading FLAC data and writing decoded samples, and
- * handling metadata and errors.  If the client also supplies seek-related
- * callback, the decoder function for sample-accurate seeking within the
- * FLAC input is also available.  When decoding from a file, the client
- * needs only supply a filename or open \c FILE* and write/metadata/error
- * callbacks; the rest of the callbacks are supplied internally.  For more
- * info see the \link flac_stream_decoder stream decoder \endlink module.

-/** \defgroup flac_stream_decoder FLAC/stream_decoder.h: stream decoder interface
- *  \ingroup flac_decoder
- *
- *  \brief
- *  This module contains the functions which implement the stream
- *  decoder.
- *
- * The stream decoder can decode native FLAC, and optionally Ogg FLAC
- * (check FLAC_API_SUPPORTS_OGG_FLAC) streams and files.
- *
- * The basic usage of this decoder is as follows:
- * - The program creates an instance of a decoder using
- *   FLAC__stream_decoder_new().
- * - The program overrides the default settings using
- *   FLAC__stream_decoder_set_*() functions.
- * - The program initializes the instance to validate the settings and
- *   prepare for decoding using
- *   - FLAC__stream_decoder_init_stream() or FLAC__stream_decoder_init_FILE()
- *     or FLAC__stream_decoder_init_file() for native FLAC,
- *   - FLAC__stream_decoder_init_ogg_stream() or FLAC__stream_decoder_init_ogg_FILE()
- *     or FLAC__stream_decoder_init_ogg_file() for Ogg FLAC
- * - The program calls the FLAC__stream_decoder_process_*() functions
- *   to decode data, which subsequently calls the callbacks.
- * - The program finishes the decoding with FLAC__stream_decoder_finish(),
- *   which flushes the input and output and resets the decoder to the
- *   uninitialized state.
- * - The instance may be used again or deleted with
- *   FLAC__stream_decoder_delete().
- *
- * In more detail, the program will create a new instance by calling
- * FLAC__stream_decoder_new(), then call FLAC__stream_decoder_set_*()
- * functions to override the default decoder options, and call
- * one of the FLAC__stream_decoder_init_*() functions.
- *
- * There are three initialization functions for native FLAC, one for
- * setting up the decoder to decode FLAC data from the client via
- * callbacks, and two for decoding directly from a FLAC file.
- *
- * For decoding via callbacks, use FLAC__stream_decoder_init_stream().
- * You must also supply several callbacks for handling I/O.  Some (like
- * seeking) are optional, depending on the capabilities of the input.
- *
- * For decoding directly from a file, use FLAC__stream_decoder_init_FILE()
- * or FLAC__stream_decoder_init_file().  Then you must only supply an open
- * \c FILE* or filename and fewer callbacks; the decoder will handle
- * the other callbacks internally.
- *
- * There are three similarly-named init functions for decoding from Ogg
- * FLAC streams.  Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the
- * library has been built with Ogg support.
- *
- * Once the decoder is initialized, your program will call one of several
- * functions to start the decoding process:
- *
- * - FLAC__stream_decoder_process_single() - Tells the decoder to process at
- *   most one metadata block or audio frame and return, calling either the
- *   metadata callback or write callback, respectively, once.  If the decoder
- *   loses sync it will return with only the error callback being called.
- * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder
- *   to process the stream from the current location and stop upon reaching
- *   the first audio frame.  The client will get one metadata, write, or error
- *   callback per metadata block, audio frame, or sync error, respectively.
- * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder
- *   to process the stream from the current location until the read callback
- *   returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or
- *   FLAC__STREAM_DECODER_READ_STATUS_ABORT.  The client will get one metadata,
- *   write, or error callback per metadata block, audio frame, or sync error,
- *   respectively.
- *
- * When the decoder has finished decoding (normally or through an abort),
- * the instance is finished by calling FLAC__stream_decoder_finish(), which
- * ensures the decoder is in the correct state and frees memory.  Then the
- * instance may be deleted with FLAC__stream_decoder_delete() or initialized
- * again to decode another stream.
- *
- * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method.
- * At any point after the stream decoder has been initialized, the client can
- * call this function to seek to an exact sample within the stream.
- * Subsequently, the first time the write callback is called it will be
- * passed a (possibly partial) block starting at that sample.
- *
- * If the client cannot seek via the callback interface provided, but still
- * has another way of seeking, it can flush the decoder using
- * FLAC__stream_decoder_flush() and start feeding data from the new position
- * through the read callback.
- *
- * The stream decoder also provides MD5 signature checking.  If this is
- * turned on before initialization, FLAC__stream_decoder_finish() will
- * report when the decoded MD5 signature does not match the one stored
- * in the STREAMINFO block.  MD5 checking is automatically turned off
- * (until the next FLAC__stream_decoder_reset()) if there is no signature
- * in the STREAMINFO block or when a seek is attempted.
- *
- * The FLAC__stream_decoder_set_metadata_*() functions deserve special
- * attention.  By default, the decoder only calls the metadata_callback for
- * the STREAMINFO block.  These functions allow you to tell the decoder
- * explicitly which blocks to parse and return via the metadata_callback
- * and/or which to skip.  Use a FLAC__stream_decoder_set_metadata_respond_all(),
- * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(),
- * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify
- * which blocks to return.  Remember that metadata blocks can potentially
- * be big (for example, cover art) so filtering out the ones you don't
- * use can reduce the memory requirements of the decoder.  Also note the
- * special forms FLAC__stream_decoder_set_metadata_respond_application(id)
- * and FLAC__stream_decoder_set_metadata_ignore_application(id) for
- * filtering APPLICATION blocks based on the application ID.
- *
- * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but
- * they still can legally be filtered from the metadata_callback.
- *
- * \note
- * The "set" functions may only be called when the decoder is in the
- * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after
- * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but
- * before FLAC__stream_decoder_init_*().  If this is the case they will
- * return \c true, otherwise \c false.
- *
- * \note
- * FLAC__stream_decoder_finish() resets all settings to the constructor
- * defaults, including the callbacks.

-/** \defgroup flac_stream_encoder FLAC/stream_encoder.h: stream encoder interface
- *  \ingroup flac_encoder
- *
- *  \brief
- *  This module contains the functions which implement the stream
- *  encoder.
- *
- * The stream encoder can encode to native FLAC, and optionally Ogg FLAC
- * (check FLAC_API_SUPPORTS_OGG_FLAC) streams and files.
- *
- * The basic usage of this encoder is as follows:
- * - The program creates an instance of an encoder using
- *   FLAC__stream_encoder_new().
- * - The program overrides the default settings using
- *   FLAC__stream_encoder_set_*() functions.  At a minimum, the following
- *   functions should be called:
- *   - FLAC__stream_encoder_set_channels()
- *   - FLAC__stream_encoder_set_bits_per_sample()
- *   - FLAC__stream_encoder_set_sample_rate()
- *   - FLAC__stream_encoder_set_ogg_serial_number() (if encoding to Ogg FLAC)
- *   - FLAC__stream_encoder_set_total_samples_estimate() (if known)
- * - If the application wants to control the compression level or set its own
- *   metadata, then the following should also be called:
- *   - FLAC__stream_encoder_set_compression_level()
- *   - FLAC__stream_encoder_set_verify()
- *   - FLAC__stream_encoder_set_metadata()
- * - The rest of the set functions should only be called if the client needs
- *   exact control over how the audio is compressed; thorough understanding
- *   of the FLAC format is necessary to achieve good results.
- * - The program initializes the instance to validate the settings and
- *   prepare for encoding using
- *   - FLAC__stream_encoder_init_stream() or FLAC__stream_encoder_init_FILE()
- *     or FLAC__stream_encoder_init_file() for native FLAC
- *   - FLAC__stream_encoder_init_ogg_stream() or FLAC__stream_encoder_init_ogg_FILE()
- *     or FLAC__stream_encoder_init_ogg_file() for Ogg FLAC
- * - The program calls FLAC__stream_encoder_process() or
- *   FLAC__stream_encoder_process_interleaved() to encode data, which
- *   subsequently calls the callbacks when there is encoder data ready
- *   to be written.
- * - The program finishes the encoding with FLAC__stream_encoder_finish(),
- *   which causes the encoder to encode any data still in its input pipe,
- *   update the metadata with the final encoding statistics if output
- *   seeking is possible, and finally reset the encoder to the
- *   uninitialized state.
- * - The instance may be used again or deleted with
- *   FLAC__stream_encoder_delete().
- *
- * In more detail, the stream encoder functions similarly to the
- * \link flac_stream_decoder stream decoder \endlink, but has fewer
- * callbacks and more options.  Typically the client will create a new
- * instance by calling FLAC__stream_encoder_new(), then set the necessary
- * parameters with FLAC__stream_encoder_set_*(), and initialize it by
- * calling one of the FLAC__stream_encoder_init_*() functions.
- *
- * Unlike the decoders, the stream encoder has many options that can
- * affect the speed and compression ratio.  When setting these parameters
- * you should have some basic knowledge of the format (see the
- * <A HREF="../documentation_format_overview.html">user-level documentation</A>
- * or the <A HREF="../format.html">formal description</A>).  The
- * FLAC__stream_encoder_set_*() functions themselves do not validate the
- * values as many are interdependent.  The FLAC__stream_encoder_init_*()
- * functions will do this, so make sure to pay attention to the state
- * returned by FLAC__stream_encoder_init_*() to make sure that it is
- * FLAC__STREAM_ENCODER_INIT_STATUS_OK.  Any parameters that are not set
- * before FLAC__stream_encoder_init_*() will take on the defaults from
- * the constructor.
- *
- * There are three initialization functions for native FLAC, one for
- * setting up the encoder to encode FLAC data to the client via
- * callbacks, and two for encoding directly to a file.
- *
- * For encoding via callbacks, use FLAC__stream_encoder_init_stream().
- * You must also supply a write callback which will be called anytime
- * there is raw encoded data to write.  If the client can seek the output
- * it is best to also supply seek and tell callbacks, as this allows the
- * encoder to go back after encoding is finished to write back
- * information that was collected while encoding, like seek point offsets,
- * frame sizes, etc.
- *
- * For encoding directly to a file, use FLAC__stream_encoder_init_FILE()
- * or FLAC__stream_encoder_init_file().  Then you must only supply a
- * filename or open \c FILE*; the encoder will handle all the callbacks
- * internally.  You may also supply a progress callback for periodic
- * notification of the encoding progress.
- *
- * There are three similarly-named init functions for encoding to Ogg
- * FLAC streams.  Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the
- * library has been built with Ogg support.
- *
- * The call to FLAC__stream_encoder_init_*() currently will also immediately
- * call the write callback several times, once with the \c fLaC signature,
- * and once for each encoded metadata block.  Note that for Ogg FLAC
- * encoding you will usually get at least twice the number of callbacks than
- * with native FLAC, one for the Ogg page header and one for the page body.
- *
- * After initializing the instance, the client may feed audio data to the
- * encoder in one of two ways:
- *
- * - Channel separate, through FLAC__stream_encoder_process() - The client
- *   will pass an array of pointers to buffers, one for each channel, to
- *   the encoder, each of the same length.  The samples need not be
- *   block-aligned, but each channel should have the same number of samples.
- * - Channel interleaved, through
- *   FLAC__stream_encoder_process_interleaved() - The client will pass a single
- *   pointer to data that is channel-interleaved (i.e. channel0_sample0,
- *   channel1_sample0, ... , channelN_sample0, channel0_sample1, ...).
- *   Again, the samples need not be block-aligned but they must be
- *   sample-aligned, i.e. the first value should be channel0_sample0 and
- *   the last value channelN_sampleM.
- *
- * Note that for either process call, each sample in the buffers should be a
- * signed integer, right-justified to the resolution set by
- * FLAC__stream_encoder_set_bits_per_sample().  For example, if the resolution
- * is 16 bits per sample, the samples should all be in the range [-32768,32767].
- *
- * When the client is finished encoding data, it calls
- * FLAC__stream_encoder_finish(), which causes the encoder to encode any
- * data still in its input pipe, and call the metadata callback with the
- * final encoding statistics.  Then the instance may be deleted with
- * FLAC__stream_encoder_delete() or initialized again to encode another
- * stream.
- *
- * For programs that write their own metadata, but that do not know the
- * actual metadata until after encoding, it is advantageous to instruct
- * the encoder to write a PADDING block of the correct size, so that
- * instead of rewriting the whole stream after encoding, the program can
- * just overwrite the PADDING block.  If only the maximum size of the
- * metadata is known, the program can write a slightly larger padding
- * block, then split it after encoding.
- *
- * Make sure you understand how lengths are calculated.  All FLAC metadata
- * blocks have a 4 byte header which contains the type and length.  This
- * length does not include the 4 bytes of the header.  See the format page
- * for the specification of metadata blocks and their lengths.
- *
- * \note
- * If you are writing the FLAC data to a file via callbacks, make sure it
- * is open for update (e.g. mode "w+" for stdio streams).  This is because
- * after the first encoding pass, the encoder will try to seek back to the
- * beginning of the stream, to the STREAMINFO block, to write some data
- * there.  (If using FLAC__stream_encoder_init*_file() or
- * FLAC__stream_encoder_init*_FILE(), the file is managed internally.)
- *
- * \note
- * The "set" functions may only be called when the encoder is in the
- * state FLAC__STREAM_ENCODER_UNINITIALIZED, i.e. after
- * FLAC__stream_encoder_new() or FLAC__stream_encoder_finish(), but
- * before FLAC__stream_encoder_init_*().  If this is the case they will
- * return \c true, otherwise \c false.
- *
- * \note
- * FLAC__stream_encoder_finish() resets all settings to the constructor
- * defaults.

- *  supply less data and modify the byte count but must be careful not to
- *  overflow the buffer.  The callback then returns a status code chosen from
- *  FLAC__StreamEncoderReadStatus.
- *
- * Here is an example of a read callback for stdio streams:
- * \code
- * FLAC__StreamEncoderReadStatus read_cb(const FLAC__StreamEncoder *encoder, FLAC__byte buffer[], size_t *bytes, void *client_data)
- * {
- *   FILE *file = ((MyClientData*)client_data)->file;

- * \c punchout_tukey(n[/ov[/P]]), \c welch.
- *
- * For \c gauss(STDDEV), STDDEV specifies the standard deviation
- * (0<STDDEV<=0.5).
- *
- * For \c tukey(P), P specifies the fraction of the window that is
- * tapered (0<=P<=1).  P=0 corresponds to \c rectangle and P=1
- * corresponds to \c hann.
- *
- * Specifying \c partial_tukey or \c punchout_tukey works a little
- * different. These do not specify a single apodization function, but
- * a series of them with some overlap. partial_tukey specifies a series
- * of small windows (all treated separately) while punchout_tukey
- * specifies a series of windows that have a hole in them. In this way,
- * the predictor is constructed with only a part of the block, which
- * helps in case a block consists of dissimilar parts.
- *
- * The three parameters that can be specified for the functions are
- * n, ov and P. n is the number of functions to add, ov is the overlap
- * of the windows in case of partial_tukey and the overlap in the gaps
- * in case of punchout_tukey. P is the fraction of the window that is
- * tapered, like with a regular tukey window. The function can be
- * specified with only a number, a number and an overlap, or a number
- * an overlap and a P, for example, partial_tukey(3), partial_tukey(3/0.3)
- * and partial_tukey(3/0.3/0.5) are all valid. ov should be smaller than 1
- * and can be negative.
- *
- * Example specifications are \c "blackman" or
- * \c "hann;triangle;tukey(0.5);tukey(0.25);tukey(0.125)"
- *
- * Any function that is specified erroneously is silently dropped.  Up
- * to 32 functions are kept, the rest are dropped.  If the specification
- * is empty the encoder defaults to \c "tukey(0.5)".
- *
- * When more than one function is specified, then for every subframe the
- * encoder will try each of them separately and choose the window that
- * results in the smallest compressed subframe.
- *
- * Note that each function specified causes the encoder to occupy a

- *
- * \note

- *
- * \note
- * The STREAMINFO block is always written and no STREAMINFO block may

- *
- * \note
- * By default the encoder does not create a SEEKTABLE.  If one is supplied

- * by itself this is not very useful as the client will not know the stream
- * offsets for the seekpoints ahead of time.  In order to get a proper
- * seektable the client must support seeking.  See next note.
- *
- * \note
- * SEEKTABLE blocks are handled specially.  Since you will not know
- * the values for the seek point stream offsets, you should pass in
- * a SEEKTABLE 'template', that is, a SEEKTABLE object with the
- * required sample numbers (or placeholder points), with \c 0 for the
- * \a frame_samples and \a stream_offset fields for each point.  If the
- * client has specified that it supports seeking by providing a seek
- * callback to FLAC__stream_encoder_init_stream() or both seek AND read
- * callback to FLAC__stream_encoder_init_ogg_stream() (or by using
- * FLAC__stream_encoder_init*_file() or FLAC__stream_encoder_init*_FILE()),
- * then while it is encoding the encoder will fill the stream offsets in
- * for you and when encoding is finished, it will seek back and write the
- * real values into the SEEKTABLE block in the stream.  There are helper
- * routines for manipulating seektable template blocks; see metadata.h:
- * FLAC__metadata_object_seektable_template_*().  If the client does
- * not support seeking, the SEEKTABLE will have inaccurate offsets which
- * will slow down or remove the ability to seek in the FLAC stream.
- *
- * \note
- * The encoder instance \b will modify the first \c SEEKTABLE block
- * as it transforms the template to a valid seektable while encoding,
- * but it is still up to the caller to free all metadata blocks after
- * encoding.
- *
- * \note
- * A VORBIS_COMMENT block may be supplied.  The vendor string in it
- * will be ignored.  libFLAC will use it's own vendor string. libFLAC
- * will not modify the passed-in VORBIS_COMMENT's vendor string, it
- * will simply write it's own into the stream.  If no VORBIS_COMMENT
- * block is present in the \a metadata array, libFLAC will write an
- * empty one, containing only the vendor string.
- *
- * \note The Ogg FLAC mapping requires that the VORBIS_COMMENT block be
- * the second metadata block of the stream.  The encoder already supplies
- * the STREAMINFO block automatically.  If \a metadata does not contain a
- * VORBIS_COMMENT block, the encoder will supply that too.  Otherwise, if
- * \a metadata does contain a VORBIS_COMMENT block and it is not the
- * first, the init function will reorder \a metadata by moving the
- * VORBIS_COMMENT block to the front; the relative ordering of the other
- * blocks will remain as they were.

-	NOTE:
-	I cannot get the vanilla getopt code to work (i.e. compile only what
-	is needed and not duplicate symbols found in the standard library)
-	on all the platforms that FLAC supports.  In particular the gating
-	of code with the ELIDE_CODE #define is not accurate enough on systems
-	that are POSIX but not glibc.  If someone has a patch that works on
-	GNU/Linux, Darwin, AND Solaris please submit it on the project page:
-		https://sourceforge.net/p/flac/patches/
-
-	In the meantime I have munged the global symbols and removed gates
-	around code, while at the same time trying to touch the original as
-	little as possible.

-
-   If the field `flag' is not NULL, it points to a variable that is set
-   to the value given in the field `val' when the option is found, but
-   left unchanged if the option is not found.
-
-   To have a long-named option do something other than set an `int' to
-   a compiled-in constant, such as set a value from `share__optarg', set the
-   option's `flag' field to zero and its `val' field to a nonzero
-   value (the equivalent single-letter option character, if there is
-   one).  For long options that have a zero `flag' field, `share__getopt'

-   there are no more options.  For unrecognized options, or options
-   missing arguments, `share__optopt' is set to the option letter, and '?' is

-
-   The OPTS string is a list of characters which are recognized option

- * This code implements the MD5 message-digest algorithm.
- * The algorithm is due to Ron Rivest.  This code was
- * written by Colin Plumb in 1993, no copyright is claimed.
- * This code is in the public domain; do with it what you wish.
- *
- * Equivalent code is available from RSA Data Security, Inc.
- * This code has been tested against that, and is equivalent,
- * except that you don't need to include two pages of legalese
- * with every copy.
- *
- * To compute the message digest of a chunk of bytes, declare an
- * MD5Context structure, pass it to MD5Init, call MD5Update as
- * needed on buffers full of bytes, and then call MD5Final, which
- * will fill a supplied 16-byte array with the digest.
- *
- * Changed so as no longer to depend on Colin Plumb's `usual.h' header
- * definitions; now uses stuff from dpkg's config.h.
- *  - Ian Jackson <ijackson@nyx.cs.du.edu>.
- * Still in the public domain.
- *
- * Josh Coalson: made some changes to integrate with libFLAC.

-	 * but how much it asks for depends on how much free space it has in
-	 * its internal buffer.  It does not try to grow its internal buffer
-	 * to accomodate a whole frame because then the internal buffer size
-	 * could not be limited, which is necessary in embedded applications.
-	 *
-	 * Ogg however grows its internal buffer until a whole page is present;
-	 * only then can you get decoded data out.  So we can't just ask for
-	 * the same number of bytes from Ogg, then pass what's decoded down to
-	 * libFLAC.  If what libFLAC is asking for will not contain a whole
-	 * page, then we will get no data from ogg_sync_pageout(), and at the
-	 * same time cannot just read more data from the client for the purpose
-	 * of getting a whole decoded page because the decoded size might be
-	 * larger than libFLAC's internal buffer.
-	 *
-	 * Instead, whenever this read callback wrapper is called, we will
-	 * continually request data from the client until we have at least one
-	 * page, and manage pages internally so that we can send pieces of
-	 * pages down to libFLAC in such a way that we obey its size
-	 * requirement.  To limit the amount of callbacks, we will always try

-   to be given in any order, even with programs that were not written to
-   expect this.
-
-   RETURN_IN_ORDER is an option available to programs that were written
-   to expect options and other ARGV-elements in any order and that care about
-   the ordering of the two.  We describe each non-option ARGV-element
-   as if it were the argument of an option with character code 1.
-   Using `-' as the first character of the list of option characters
-   selects this mode of operation.
-
-   The special argument `--' forces an end of option-scanning regardless
-   of the value of `ordering'.  In the case of RETURN_IN_ORDER, only

-/* Scan elements of ARGV (whose length is ARGC) for option characters
-   given in OPTSTRING.
-
-   If an element of ARGV starts with '-', and is not exactly "-" or "--",
-   then it is an option element.  The characters of this element
-   (aside from the initial '-') are option characters.  If `share__getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `share__getopt' finds another option character, it returns that character,
-   updating `share__optind' and `nextchar' so that the next call to `share__getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `share__getopt' returns -1.
-   Then `share__optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `share__opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `share__optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `share__optarg', otherwise `share__optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `share__getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct share__option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most
-   recent call.
-
-   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
-   long-named options.  */

+# libchdr
+
+libchdr is a standalone library for reading MAME's CHDv1-v5 formats.
+
+The code is based off of MAME's old C codebase which read up to CHDv4 with OS-dependent features removed, and CHDv5 support backported from MAME's current C++ codebase.
+
+libchdr is licensed under the BSD 3-Clause (see [LICENSE.txt](LICENSE.txt)) and uses third party libraries that are each distributed under their own terms (see each library's license in [deps/](deps/)).

+RELEASE NOTES - v0.12.0
+=======================
+Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
+
+
+Improved Client-Defined Memory Allocation
+-----------------------------------------
+The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
+existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
+allocation callbacks are specified.
+
+To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
+
+    void* my_malloc(size_t sz, void* pUserData)
+    {
+        return malloc(sz);
+    }
+    void* my_realloc(void* p, size_t sz, void* pUserData)
+    {
+        return realloc(p, sz);
+    }
+    void my_free(void* p, void* pUserData)
+    {
+        free(p);
+    }
+
+    ...
+
+    drflac_allocation_callbacks allocationCallbacks;
+    allocationCallbacks.pUserData = &myData;
+    allocationCallbacks.onMalloc  = my_malloc;
+    allocationCallbacks.onRealloc = my_realloc;
+    allocationCallbacks.onFree    = my_free;
+    drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
+
+The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
+
+Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
+DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
+
+Every API that opens a drflac object now takes this extra parameter. These include the following:
+
+    drflac_open()
+    drflac_open_relaxed()
+    drflac_open_with_metadata()
+    drflac_open_with_metadata_relaxed()
+    drflac_open_file()
+    drflac_open_file_with_metadata()
+    drflac_open_memory()
+    drflac_open_memory_with_metadata()
+    drflac_open_and_read_pcm_frames_s32()
+    drflac_open_and_read_pcm_frames_s16()
+    drflac_open_and_read_pcm_frames_f32()
+    drflac_open_file_and_read_pcm_frames_s32()
+    drflac_open_file_and_read_pcm_frames_s16()
+    drflac_open_file_and_read_pcm_frames_f32()
+    drflac_open_memory_and_read_pcm_frames_s32()
+    drflac_open_memory_and_read_pcm_frames_s16()
+    drflac_open_memory_and_read_pcm_frames_f32()
+
+
+
+Optimizations
+-------------
+Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly
+improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes
+advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which
+means it will be disabled when DR_FLAC_NO_CRC is used.
+
+The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in
+particular. 16-bit streams should also see some improvement.
+
+drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32
+to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths.
+
+A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo
+channel reconstruction which is the last part of the decoding process.
+
+The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when
+compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at
+compile time and the REV instruction requires ARM architecture version 6.
+
+An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling.
+
+
+Removed APIs
+------------
+The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0:
+
+    drflac_read_s32()                   -> drflac_read_pcm_frames_s32()
+    drflac_read_s16()                   -> drflac_read_pcm_frames_s16()
+    drflac_read_f32()                   -> drflac_read_pcm_frames_f32()
+    drflac_seek_to_sample()             -> drflac_seek_to_pcm_frame()
+    drflac_open_and_decode_s32()        -> drflac_open_and_read_pcm_frames_s32()
+    drflac_open_and_decode_s16()        -> drflac_open_and_read_pcm_frames_s16()
+    drflac_open_and_decode_f32()        -> drflac_open_and_read_pcm_frames_f32()
+    drflac_open_and_decode_file_s32()   -> drflac_open_file_and_read_pcm_frames_s32()
+    drflac_open_and_decode_file_s16()   -> drflac_open_file_and_read_pcm_frames_s16()

+
+
+/*
+Introduction
+============
+dr_flac is a single file library. To use it, do something like the following in one .c file.
+
+    ```c
+    #define DR_FLAC_IMPLEMENTATION
+    #include "dr_flac.h"
+    ```
+
+You can then #include this file in other parts of the program as you would with any other header file. To decode audio data, do something like the following:
+
+    ```c
+    drflac* pFlac = drflac_open_file("MySong.flac", NULL);
+    if (pFlac == NULL) {
+        // Failed to open FLAC file
+    }
+
+    drflac_int32* pSamples = malloc(pFlac->totalPCMFrameCount * pFlac->channels * sizeof(drflac_int32));
+    drflac_uint64 numberOfInterleavedSamplesActuallyRead = drflac_read_pcm_frames_s32(pFlac, pFlac->totalPCMFrameCount, pSamples);
+    ```
+
+The drflac object represents the decoder. It is a transparent type so all the information you need, such as the number of channels and the bits per sample,
+should be directly accessible - just make sure you don't change their values. Samples are always output as interleaved signed 32-bit PCM. In the example above
+a native FLAC stream was opened, however dr_flac has seamless support for Ogg encapsulated FLAC streams as well.
+
+You do not need to decode the entire stream in one go - you just specify how many samples you'd like at any given time and the decoder will give you as many
+samples as it can, up to the amount requested. Later on when you need the next batch of samples, just call it again. Example:
+
+    ```c
+    while (drflac_read_pcm_frames_s32(pFlac, chunkSizeInPCMFrames, pChunkSamples) > 0) {
+        do_something();
+    }
+    ```
+
+You can seek to a specific PCM frame with `drflac_seek_to_pcm_frame()`.
+
+If you just want to quickly decode an entire FLAC file in one go you can do something like this:
+
+    ```c
+    unsigned int channels;
+    unsigned int sampleRate;
+    drflac_uint64 totalPCMFrameCount;
+    drflac_int32* pSampleData = drflac_open_file_and_read_pcm_frames_s32("MySong.flac", &channels, &sampleRate, &totalPCMFrameCount, NULL);
+    if (pSampleData == NULL) {
+        // Failed to open and decode FLAC file.
+    }
+
+    ...
+
+    drflac_free(pSampleData, NULL);
+    ```
+
+You can read samples as signed 16-bit integer and 32-bit floating-point PCM with the *_s16() and *_f32() family of APIs respectively, but note that these
+should be considered lossy.
+
+
+If you need access to metadata (album art, etc.), use `drflac_open_with_metadata()`, `drflac_open_file_with_metdata()` or `drflac_open_memory_with_metadata()`.
+The rationale for keeping these APIs separate is that they're slightly slower than the normal versions and also just a little bit harder to use. dr_flac
+reports metadata to the application through the use of a callback, and every metadata block is reported before `drflac_open_with_metdata()` returns.
+
+The main opening APIs (`drflac_open()`, etc.) will fail if the header is not present. The presents a problem in certain scenarios such as broadcast style
+streams or internet radio where the header may not be present because the user has started playback mid-stream. To handle this, use the relaxed APIs:
+    
+    `drflac_open_relaxed()`
+    `drflac_open_with_metadata_relaxed()`
+
+It is not recommended to use these APIs for file based streams because a missing header would usually indicate a corrupt or perverse file. In addition, these
+APIs can take a long time to initialize because they may need to spend a lot of time finding the first frame.
+
+
+
+Build Options
+=============
+#define these options before including this file.
+
+#define DR_FLAC_NO_STDIO
+  Disable `drflac_open_file()` and family.
+
+#define DR_FLAC_NO_OGG
+  Disables support for Ogg/FLAC streams.
+
+#define DR_FLAC_BUFFER_SIZE <number>
+  Defines the size of the internal buffer to store data from onRead(). This buffer is used to reduce the number of calls back to the client for more data.
+  Larger values means more memory, but better performance. My tests show diminishing returns after about 4KB (which is the default). Consider reducing this if
+  you have a very efficient implementation of onRead(), or increase it if it's very inefficient. Must be a multiple of 8.
+
+#define DR_FLAC_NO_CRC
+  Disables CRC checks. This will offer a performance boost when CRC is unnecessary. This will disable binary search seeking. When seeking, the seek table will
+  be used if available. Otherwise the seek will be performed using brute force.
+
+#define DR_FLAC_NO_SIMD
+  Disables SIMD optimizations (SSE on x86/x64 architectures, NEON on ARM architectures). Use this if you are having compatibility issues with your compiler.
+
+
+
+Notes
+=====
+- dr_flac does not support changing the sample rate nor channel count mid stream.
+- dr_flac is not thread-safe, but its APIs can be called from any thread so long as you do your own synchronization.
+- When using Ogg encapsulation, a corrupted metadata block will result in `drflac_open_with_metadata()` and `drflac_open()` returning inconsistent samples due
+  to differences in corrupted stream recorvery logic between the two APIs.

+
+This is the lowest level function for opening a FLAC stream. You can also use `drflac_open_file()` and `drflac_open_memory()` to open the stream from a file or
+from a block of memory respectively.
+
+The STREAMINFO block must be present for this to succeed. Use `drflac_open_relaxed()` to open a FLAC stream where the header may not be present.

+
+This is slower than `drflac_open()`, so avoid this one if you don't need metadata. Internally, this will allocate and free memory on the heap for every
+metadata block except for STREAMINFO and PADDING blocks.
+
+The caller is notified of the metadata via the `onMeta` callback. All metadata blocks will be handled before the function returns. This callback takes a
+pointer to a `drflac_metadata` object which is a union containing the data of all relevant metadata blocks. Use the `type` member to discriminate against
+the different metadata types.
+
+The STREAMINFO block must be present for this to succeed. Use `drflac_open_with_metadata_relaxed()` to open a FLAC stream where the header may not be present.
+
+Note that this will behave inconsistently with `drflac_open()` if the stream is an Ogg encapsulated stream and a metadata block is corrupted. This is due to
+the way the Ogg stream recovers from corrupted pages. When `drflac_open_with_metadata()` is being used, the open routine will try to read the contents of the
+metadata block, whereas `drflac_open()` will simply seek past it (for the sake of efficiency). This inconsistency can result in different samples being
+returned depending on whether or not the stream is being opened with metadata.

+    to achieve good performance, however on GCC and Clang it's a little bit more annoying. The __builtin_clzl() and __builtin_clzll() intrinsics leave
+    it undefined as to the return value when `x` is 0. We need this to be well defined as returning 32 or 64, depending on whether or not it's a 32- or
+    64-bit build. To work around this we would need to add a conditional to check for the x = 0 case, but this creates unnecessary inefficiency. To work
+    around this problem I have written some inline assembly to emit the LZCNT (x86) or CLZ (ARM) instruction directly which removes the need to include
+    the conditional. This has worked well in the past, but for some reason Clang's MSVC compatible driver, clang-cl, does not seem to be handling this
+    in the same way as the normal Clang driver. It seems that `clang-cl` is just outputting the wrong results sometimes, maybe due to some register
+    getting clobbered?
+
+    I'm not sure if this is a bug with dr_flac's inlined assembly (most likely), a bug in `clang-cl` or just a misunderstanding on my part with inline
+    assembly rules for `clang-cl`. If somebody can identify an error in dr_flac's inlined assembly I'm happy to get that fixed.
+
+    Fortunately there is an easy workaround for this. Clang implements MSVC-specific intrinsics for compatibility. It also defines _MSC_VER for extra
+    compatibility. We can therefore just check for _MSC_VER and use the MSVC intrinsic which, fortunately for us, Clang supports. It would still be nice
+    to know how to fix the inlined assembly for correctness sake, however.

+          2) Use Ogg's framing system.
+
+        Both of these options have their own pros and cons. Using the native FLAC decoder is slower because it needs to
+        do a full decode of the frame. Using Ogg's framing system is faster, but more complicated and involves some code
+        duplication for the decoding of frame headers.
+
+        Another thing to consider is that using the Ogg framing system will perform direct seeking of the physical Ogg
+        bitstream. This is important to consider because it means we cannot read data from the drflac_bs object using the
+        standard drflac__*() APIs because that will read in extra data for its own internal caching which in turn breaks
+        the positioning of the read pointer of the physical Ogg bitstream. Therefore, anything that would normally be read
+        using the native FLAC decoding APIs, such as drflac__read_next_flac_frame_header(), need to be re-implemented so as to
+        avoid the use of the drflac_bs object.
+
+        Considering these issues, I have decided to use the slower native FLAC decoding method for the following reasons:
+          1) Seeking is already partially accelerated using Ogg's paging system in the code block above.
+          2) Seeking in an Ogg encapsulated FLAC stream is probably quite uncommon.
+          3) Simplicity.

+  - Fix some Clang Static Analyzer warnings.
+  - Fix an unused variable warning.
+
+v0.12.0 - 2019-09-23
+  - API CHANGE: Add support for user defined memory allocation routines. This system allows the program to specify their own memory allocation
+    routines with a user data pointer for client-specific contextual data. This adds an extra parameter to the end of the following APIs:
+    - drflac_open()
+    - drflac_open_relaxed()
+    - drflac_open_with_metadata()
+    - drflac_open_with_metadata_relaxed()
+    - drflac_open_file()
+    - drflac_open_file_with_metadata()
+    - drflac_open_memory()
+    - drflac_open_memory_with_metadata()
+    - drflac_open_and_read_pcm_frames_s32()
+    - drflac_open_and_read_pcm_frames_s16()
+    - drflac_open_and_read_pcm_frames_f32()
+    - drflac_open_file_and_read_pcm_frames_s32()
+    - drflac_open_file_and_read_pcm_frames_s16()
+    - drflac_open_file_and_read_pcm_frames_f32()
+    - drflac_open_memory_and_read_pcm_frames_s32()
+    - drflac_open_memory_and_read_pcm_frames_s16()
+    - drflac_open_memory_and_read_pcm_frames_f32()
+    Set this extra parameter to NULL to use defaults which is the same as the previous behaviour. Setting this NULL will use
+    DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE.
+  - Remove deprecated APIs:
+    - drflac_read_s32()
+    - drflac_read_s16()
+    - drflac_read_f32()
+    - drflac_seek_to_sample()
+    - drflac_open_and_decode_s32()
+    - drflac_open_and_decode_s16()
+    - drflac_open_and_decode_f32()
+    - drflac_open_and_decode_file_s32()
+    - drflac_open_and_decode_file_s16()
+    - drflac_open_and_decode_file_f32()
+    - drflac_open_and_decode_memory_s32()
+    - drflac_open_and_decode_memory_s16()
+    - drflac_open_and_decode_memory_f32()
+  - Remove drflac.totalSampleCount which is now replaced with drflac.totalPCMFrameCount. You can emulate drflac.totalSampleCount
+    by doing pFlac->totalPCMFrameCount*pFlac->channels.
+  - Rename drflac.currentFrame to drflac.currentFLACFrame to remove ambiguity with PCM frames.
+  - Fix errors when seeking to the end of a stream.
+  - Optimizations to seeking.
+  - SSE improvements and optimizations.
+  - ARM NEON optimizations.
+  - Optimizations to drflac_read_pcm_frames_s16().
+  - Optimizations to drflac_read_pcm_frames_s32().
+
+v0.11.10 - 2019-06-26
+  - Fix a compiler error.
+
+v0.11.9 - 2019-06-16
+  - Silence some ThreadSanitizer warnings.
+
+v0.11.8 - 2019-05-21
+  - Fix warnings.
+
+v0.11.7 - 2019-05-06
+  - C89 fixes.
+
+v0.11.6 - 2019-05-05
+  - Add support for C89.
+  - Fix a compiler warning when CRC is disabled.
+  - Change license to choice of public domain or MIT-0.
+
+v0.11.5 - 2019-04-19
+  - Fix a compiler error with GCC.
+
+v0.11.4 - 2019-04-17
+  - Fix some warnings with GCC when compiling with -std=c99.
+
+v0.11.3 - 2019-04-07
+  - Silence warnings with GCC.
+
+v0.11.2 - 2019-03-10
+  - Fix a warning.
+
+v0.11.1 - 2019-02-17
+  - Fix a potential bug with seeking.
+
+v0.11.0 - 2018-12-16
+  - API CHANGE: Deprecated drflac_read_s32(), drflac_read_s16() and drflac_read_f32() and replaced them with
+    drflac_read_pcm_frames_s32(), drflac_read_pcm_frames_s16() and drflac_read_pcm_frames_f32(). The new APIs take
+    and return PCM frame counts instead of sample counts. To upgrade you will need to change the input count by
+    dividing it by the channel count, and then do the same with the return value.
+  - API_CHANGE: Deprecated drflac_seek_to_sample() and replaced with drflac_seek_to_pcm_frame(). Same rules as
+    the changes to drflac_read_*() apply.
+  - API CHANGE: Deprecated drflac_open_and_decode_*() and replaced with drflac_open_*_and_read_*(). Same rules as
+    the changes to drflac_read_*() apply.
+  - Optimizations.
+
+v0.10.0 - 2018-09-11
+  - Remove the DR_FLAC_NO_WIN32_IO option and the Win32 file IO functionality. If you need to use Win32 file IO you
+    need to do it yourself via the callback API.
+  - Fix the clang build.
+  - Fix undefined behavior.
+  - Fix errors with CUESHEET metdata blocks.
+  - Add an API for iterating over each cuesheet track in the CUESHEET metadata block. This works the same way as the
+    Vorbis comment API.
+  - Other miscellaneous bug fixes, mostly relating to invalid FLAC streams.
+  - Minor optimizations.
+
+v0.9.11 - 2018-08-29
+  - Fix a bug with sample reconstruction.
+
+v0.9.10 - 2018-08-07
+  - Improve 64-bit detection.
+

+  - Fix C++ build on older versions of GCC.
+
+v0.9.8 - 2018-07-24
+  - Fix compilation errors.
+
+v0.9.7 - 2018-07-05
+  - Fix a warning.
+
+v0.9.6 - 2018-06-29
+  - Fix some typos.
+
+v0.9.5 - 2018-06-23
+  - Fix some warnings.
+
+v0.9.4 - 2018-06-14
+  - Optimizations to seeking.
+  - Clean up.
+
+v0.9.3 - 2018-05-22
+  - Bug fix.
+
+v0.9.2 - 2018-05-12
+  - Fix a compilation error due to a missing break statement.
+
+v0.9.1 - 2018-04-29
+  - Fix compilation error with Clang.
+
+v0.9 - 2018-04-24
+  - Fix Clang build.
+  - Start using major.minor.revision versioning.
+
+v0.8g - 2018-04-19
+  - Fix build on non-x86/x64 architectures.
+
+v0.8f - 2018-02-02
+  - Stop pretending to support changing rate/channels mid stream.
+
+v0.8e - 2018-02-01
+  - Fix a crash when the block size of a frame is larger than the maximum block size defined by the FLAC stream.
+  - Fix a crash the the Rice partition order is invalid.
+
+v0.8d - 2017-09-22
+  - Add support for decoding streams with ID3 tags. ID3 tags are just skipped.
+
+v0.8c - 2017-09-07
+  - Fix warning on non-x86/x64 architectures.
+
+v0.8b - 2017-08-19
+  - Fix build on non-x86/x64 architectures.
+
+v0.8a - 2017-08-13
+  - A small optimization for the Clang build.
+
+v0.8 - 2017-08-12
+  - API CHANGE: Rename dr_* types to drflac_*.
+  - Optimizations. This brings dr_flac back to about the same class of efficiency as the reference implementation.
+  - Add support for custom implementations of malloc(), realloc(), etc.
+  - Add CRC checking to Ogg encapsulated streams.
+  - Fix VC++ 6 build. This is only for the C++ compiler. The C compiler is not currently supported.
+  - Bug fixes.
+
+v0.7 - 2017-07-23
+  - Add support for opening a stream without a header block. To do this, use drflac_open_relaxed() / drflac_open_with_metadata_relaxed().
+
+v0.6 - 2017-07-22
+  - Add support for recovering from invalid frames. With this change, dr_flac will simply skip over invalid frames as if they
+    never existed. Frames are checked against their sync code, the CRC-8 of the frame header and the CRC-16 of the whole frame.
+
+v0.5 - 2017-07-16
+  - Fix typos.
+  - Change drflac_bool* types to unsigned.
+  - Add CRC checking. This makes dr_flac slower, but can be disabled with #define DR_FLAC_NO_CRC.
+
+v0.4f - 2017-03-10
+  - Fix a couple of bugs with the bitstreaming code.
+
+v0.4e - 2017-02-17
+  - Fix some warnings.
+
+v0.4d - 2016-12-26
+  - Add support for 32-bit floating-point PCM decoding.
+  - Use drflac_int* and drflac_uint* sized types to improve compiler support.
+  - Minor improvements to documentation.
+
+v0.4c - 2016-12-26
+  - Add support for signed 16-bit integer PCM decoding.
+
+v0.4b - 2016-10-23
+  - A minor change to drflac_bool8 and drflac_bool32 types.
+
+v0.4a - 2016-10-11
+  - Rename drBool32 to drflac_bool32 for styling consistency.
+
+v0.4 - 2016-09-29
+  - API/ABI CHANGE: Use fixed size 32-bit booleans instead of the built-in bool type.
+  - API CHANGE: Rename drflac_open_and_decode*() to drflac_open_and_decode*_s32().
+  - API CHANGE: Swap the order of "channels" and "sampleRate" parameters in drflac_open_and_decode*(). Rationale for this is to
+    keep it consistent with drflac_audio.
+
+v0.3f - 2016-09-21
+  - Fix a warning with GCC.
+
+v0.3e - 2016-09-18
+  - Fixed a bug where GCC 4.3+ was not getting properly identified.
+  - Fixed a few typos.
+  - Changed date formats to ISO 8601 (YYYY-MM-DD).
+
+v0.3d - 2016-06-11
+  - Minor clean up.
+

+  - Lots of clean up.
+
+v0.2b - 2016-05-10
+  - Bug fixes.
+
+v0.2a - 2016-05-10
+  - Made drflac_open_and_decode() more robust.
+  - Removed an unused debugging variable
+
+v0.2 - 2016-05-09
+  - Added support for Ogg encapsulation.
+  - API CHANGE. Have the onSeek callback take a third argument which specifies whether or not the seek
+    should be relative to the start or the current position. Also changes the seeking rules such that
+    seeking offsets will never be negative.
+  - Have drflac_open_and_decode() fail gracefully if the stream has an unknown total sample count.
+
+v0.1b - 2016-05-07
+  - Properly close the file handle in drflac_open_file() and family when the decoder fails to initialize.
+  - Removed a stale comment.
+
+v0.1a - 2016-05-05
