Subject: [SDL] error removal patch for SDL_x11dyn.c
I found that calling SDL_GetError when an error hasn't necessarily occurred is
still reporting problems from loadso regarding dynamic functions in X11. I've
added the following to my local copy to avoid revealing the 'many library
lookup' approach adopted by x11dyn.c:

You need to free the audio buffer with \fI\fBSDL_FreeWAV\fP\fR when you are done with it\&. .PP This function returns \fBNULL\fP 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\&. .SH "EXAMPLE" .PP .nf \f(CWSDL_AudioSpec wav_spec; Uint32 wav_length; Uint8 *wav_buffer; /* Load the WAV */ if( SDL_LoadWAV("test\&.wav", &wav_spec, &wav_buffer, &wav_length) == NULL ){ fprintf(stderr, "Could not open test\&.wav: %s ", SDL_GetError()); exit(-1); } \&. \&. \&. /* Do stuff with the WAV */ \&. \&. /* Free It */ SDL_FreeWAV(wav_buffer);\fR .fi .PP .SH "SEE ALSO" .PP \fI\fBSDL_AudioSpec\fR\fR, \fI\fBSDL_OpenAudio\fP\fR, \fI\fBSDL_FreeWAV\fP\fR ...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 22:58
