/*
|
|
* 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 snprintf_s
|
|
* to something that is more compatible with the behaviour of the ISO C version.
