- .SH "DESCRIPTION"
- .PP
- fBSDL_LoadWAVfP This function loads a WAVE fBfilefR into memory&.
- .PP
- If this function succeeds, it returns the given fIfBSDL_AudioSpecfPfR, filled with the audio data format of the wave data, and sets fBaudio_buffR to a fBmallocfP&'d buffer containing the audio data, and sets fBaudio_lenfR to the length of that audio buffer, in bytes&. You need to free the audio buffer with fIfBSDL_FreeWAVfPfR when you are done with it&.
- .PP
- This function returns fBNULLfP and sets the SDL error message if the wave file cannot be opened, uses an unknown data format, or is corrupt&. Currently raw, MS-ADPCM and IMA-ADPCM WAVE files are supported&.
