SDL_LoadWAV_RW
Use this function to load a WAVE from the data source, automatically freeing that source if freesrc is non-zero.
Contents
Syntax
SDL_AudioSpec* SDL_LoadWAV_RW(SDL_RWops* src,
int freesrc,
SDL_AudioSpec* spec,
Uint8** audio_buf,
Uint32* audio_len)
Function Parameters
src |
the data source for the wave file |
freesrc |
non-zero to automatically free the data source, 0 for no change |
spec |
specifies the target audio format; see SDL_AudioSpec for more info |
audio_buf |
specifies the audio buffer |
audio_len |
specifies the length of the audio buffer in bytes |
Return Value
If this function succeeds, it returns the given SDL_AudioSpec, filled with the audio data format of the wave data, and sets *audio_buf to a malloc()'d buffer containing the audio data, and sets *audio_len to the length of that audio buffer, in bytes.
This function returns NULL and sets the SDL error message if the wave file cannot be opened, uses an unknown data format, or is corrupt. Call SDL_GetError() for more information.
Code Examples
For example, to load a WAVE file, you could do:
\code
SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...);
\endcode
Remarks
Currently raw and MS-ADPCM WAVE files are supported.
You need to free the audio buffer with SDL_FreeWAV() when you are done with it.
