Date: Sun, 26 Feb 2006 11:25:09 +0900 From: Hayashi Naoyuki Subject: Re: [SDL] CVS stable again, please update SDL ports Some problems are caused on Tru64 UNIX. If applying SDL12-osf1.path, these problems are fixed. 1. configure-script say "recursive mutexes... no" and "pthread semaphores... no". checking for pthreads... yes checking for recursive mutexes... no checking for pthread semaphores... no This is because it compiled without pthread_cflags and pthread_lib when checking recursive mutexes and pthread semaphores. 2. Compiling src/audio/mme/SDL_mmeaudio.c fails. cc: Severe: ./src/audio/mme/SDL_mmeaudio.c, line 25: Cannot find file <mme_api.h> specified in #include directive. (noinclfilef) #include <mme_api.h> -^ This is because BUILD_CFLAGS is wrong. 3. Compiling src/cdrom/osf/SDL_syscdrom.c fails. cc: Warning: ./src/cdrom/osf/SDL_syscdrom.c, line 176: Too few actual parameters in the invocation of the macro "SDL_stack_alloc".

.SH "NAME"
SDL_GetRGB\- Get RGB values from a pixel in the specified pixel format\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_GetRGB\fP\fR(\fBUint32 pixel, SDL_PixelFormat *fmt, Uint8 *r, Uint8 *g, Uint8 *b\fR);
.SH "DESCRIPTION"
.PP
Get RGB component values from a pixel stored in the specified pixel format\&.
.PP
This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
