Date: Mon, 10 Nov 2003 19:57:56 +0100 From: Stephane Marchesin <stephane.marchesin@wanadoo.fr> Subject: [SDL] SDL and gcc >= 3.3.1 fix Lately, I upgraded my gcc compiler and could trigger the error described in this thread : http://www.libsdl.org/pipermail/sdl/2003-September/056163.html SDL_RLEaccel.c: In function `RLEClipBlit': SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand SDL_RLEaccel.c:845: error: invalid `asm': invalid expression as operand The attached patch fixes this issue, and is smaller than the previous one, as I was able to trigger the issue, so I could narrow it.

.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])\&.
