Fixed bug #798 kty@lavabit.com 2009-09-19 14:19:04 PDT The stable release of SDL 1.2.13 for BeOS/Haiku has a bug in BE_FindClosestFSMode that causes it to sometimes not select the best mode when going fullscreen. There are in fact two bugs in the implementation but I will not go into specifics because there is already a patch for it in the developer SVN 1.3. However I am still reporting it because I believe the following code is a better patch for the issue. The current implementation on SVN only works if it is able to find an exact match for the requested mode. However, by scanning from lowest-to-highest resolution instead of highest-to-lowest, one can find the best mode at all times

.SH "NAME"
SDL_BuildAudioCVT \- Initializes a SDL_AudioCVT structure for conversion
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_BuildAudioCVT\fP\fR(\fBSDL_AudioCVT *cvt, Uint16 src_format, Uint8 src_channels, int src_rate, Uint16 dst_format, Uint8 dst_channels, int dst_rate\fR);
.SH "DESCRIPTION"
.PP
Before an \fI\fBSDL_AudioCVT\fR\fR structure can be used to convert audio data it must be initialized with source and destination information\&. 
.PP
\fBsrc_format\fR and \fBdst_format\fR are the source and destination format of the conversion\&. (For information on audio formats see \fI\fB SDL_AudioSpec\fR\fR)\&. \fBsrc_channels\fR and \fBdst_channels\fR are the number of channels in the source and destination formats\&. Finally, \fBsrc_rate\fR and \fBdst_rate\fR are the frequency or samples-per-second of the source and destination formats\&. Once again, see \fI\fBSDL_AudioSpec\fR\fR\&.
.SH "RETURN VALUES"
.PP
Returns \fB-1\fR if the filter could not be built or 1 if it could\&.
.SH "EXAMPLES"
.PP
See \fI\fBSDL_ConvertAudio\fP\fR\&.
