Date: Fri, 18 Feb 2005 20:49:35 +0200 (EET) From: ville Subject: [SDL] Changing, at least some, anonymous enums to named enums. Howdy, Could, some if not all, enums be named rather than being anonymous enums? I ran into troubles with the enum describing event types in SDL_events.h. The problem is that an anonymous enum cannot be used in C++ templates like so: enum { C }; template< typename T > void f( T ) { } f( C );

.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])\&.
