SDL_BlitFunc SDL_CalculateBlitN ( SDL_Surface * surface )

typedef void ( SDLCALL * SDL_AudioCallback )

This function is called when the audio device needs more data.

Parameters

userdata	An application-specific parameter saved in the SDL_AudioSpec structure
stream	A pointer to the audio data buffer.
len	The length of that buffer in bytes.

Once the callback returns, the buffer will no longer be valid. Stereo samples are stored in a LRLRLR ordering.
