annotate docs/man3/SDL_Quit.3 @ 2042:3908e1f808e1

Fixed bug #292 I might be on crack here. It looks like SDL_ConvertMono() in src/audio/SDL_audiocvt.c adds the left and right channels of a stereo stream together, and clamps the new mono channel if it would overflow. Shouldn't it be dividing by 2 to average the two sample points instead of clamping? Otherwise the mono sample point's volume doubles in the conversion. This would also make the conversion faster, as it replaces two branches per sample frame with a bitwise shift. --ryan.

11 \fBSDL_Quit\fP shuts down all SDL subsystems and frees the resources allocated to them\&. This should always be called before you exit\&. For the sake of simplicity you can set \fBSDL_Quit\fP as your \fBatexit\fP call, like:

24 While using \fBatexit\fP maybe be fine for small programs, more advanced users should shut down SDL in their own cleanup code\&. Plus, using \fBatexit\fP in a library is a sure way to crash dynamically loaded code
