Set SoundFonts paths to use by supported MIDI backends.
int Mix_SetSoundFonts(const char *paths);
Paths on the filesystem where SoundFonts are available, separated by semicolons.
Returns 1 if successful, 0 on error (out of memory).
You may specify multiple paths in a single string by separating them with semicolons; they will be searched in the order listed.
This function replaces any previously-specified paths.
Passing a NULL path will remove any previously-specified paths.
Note that unlike most SDL and SDL_mixer functions, this function returns zero if there's an error, not on success. We apologize for the API design inconsistency here.
This function is available since SDL_mixer 2.0.0.
