From: Laurence Passmore Date: Mon, 26 Mar 2007 23:22:45 +0100 To: "A list for developers using the SDL library. \(includes SDL-announce\)" <sdl@lists.libsdl.org> Subject: [SDL] SDL_config_macosx.h: MAC_OS_X_VERSION_MIN_REQUIRED Hi, I just compiled my SDL application on Mac OS X with -Wundef and it threw a number of errors. Of note was: SDL_config_macosx.h: 34 warning: "MAC_OS_X_VERSION_MIN_REQUIRED" is not defined Line 34 is: #if ( (MAC_OS_X_VERSION_MIN_REQUIRED >= 1030) || (!defined (__POWERPC__)) ) Now according to this mailing on the Apple developer lists: http://lists.apple.com/archives/Xcode-users/2005/May/msg00602.html that particular #define was removed from the gcc compiler defaults and AvailabilityMacros.h (/usr/include/AvailabilityMacros.h) should be pulled in directly instead. Would someone closer to the Mac OS X version of SDL be willing to make that change please? Thanks. Laurence Passmore Homeworld SDL @ www.homeworldsdl.org

.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\&.
