+ * FLAC needs to compile and work correctly on systems with a normal ISO C99
+ * snprintf as well as Microsoft Visual Studio which has an non-standards
+ * conformant snprint_s function.
+ *
+ * The important difference occurs when the resultant string (plus string
+ * terminator) would have been longer than the supplied size parameter. When
+ * this happens, ISO C's snprintf returns the length of resultant string, but
+ * does not over-write the end of the buffer. MS's snprintf_s in this case
+ * returns -1.
+ *
+ * The _MSC_VER code below attempts to modify the return code for vsnprintf_s
+ * to something that is more compatible with the behaviour of the ISO C version.
