2014-08-16Warning fixes (23 remain...)James Haley
2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2014-04-10sound: Fix crash with large values of snd_channels.Simon Howard
Sanity check the handles passed to the i_sdlsound.c API functions and ignore requests that involve channel numbers higher than 15. This fixes a crash if the user sets the snd_channels config variable is set to a high value. This fixes #149 (thanks Alexandre Xavier).
2014-04-01Replace all snprintf() calls with M_snprintf().Simon Howard
The Windows API has an _snprintf function that is not the same as Unix's snprintf(): if the string is truncated then no trailing NUL character is appended. This makes the function unsafe. Define a replacement/wrapper called M_snprintf that works the same but always appends a trailing NUL, for safety on Windows and other OSes that behave like this. Do the same thing for vsnprintf(), and update HACKING to list snprintf/vsnprintf as forbidden functions. This fixes #375; thanks to Quasar for pointing out the different behavior of these functions.
2014-03-30sound: Fix compile when using libsamplerate.Simon Howard
The change in commit 62b5c6028.. broke the compile.
2014-03-30Eliminate some uses of sprintf() from common code.Simon Howard
As part of this, add DIR_SEPARATOR_S as a string version of the DIR_SEPARATOR macro. Change M_TempFile() to return a string allocated on the C heap rather than the zone heap. This is a first step towards fixing #371.
2014-03-29misc: Add string utility functions.Simon Howard
It's more readable to write "M_StringEndsWith(..." than doing a bunch of pointer arithmetic, and this is a common pattern. Also add M_StringStartsWith, M_StringJoin and M_StringCopy. The latter is a safe alternative for strcpy() that works the same as OpenBSD's strlcpy(). Use these functions in a few places where it makes sense.
2014-03-23sound: Add config variable to control buffer size.Simon Howard
Add snd_maxslicetime_ms variable to control the size of the output sound buffer, and reduce the default from 70ms to 28ms to match Doom's 35fps timer. Thanks to Holering for reporting this (fixes #345).
2013-09-29Add config file variable for controlling libsamplerate conversion scaleSimon Howard
factor. This is an alternative to the approach taken in the version on the trunk version, where all sounds are pre-converted at startup and adjusted based on the maximum value. Subversion-branch: /branches/v2-branch Subversion-revision: 2690

Subversion-branch: /branches/strife-branch Subversion-revision: 2289
2011-02-28Rework sound chunk allocation to use native malloc() instead of the zoneSimon Howard
