SDL_GL_SetAttribute(3)	       SDL API Reference	SDL_GL_SetAttribute(3)

NAME
       SDL_GL_SetAttribute - Set a special SDL/OpenGL attribute

SYNOPSIS
       #include	"SDL.h"

       int SDL_GL_SetAttribute(SDL_GLattr attr,	int value);

DESCRIPTION
       Sets  the  OpenGL attribute attr	to value. The attributes you set don't
       take effect until after a call  to  SDL_SetVideoMode.  You  should  use
       SDL_GL_GetAttribute to check the	values after a SDL_SetVideoMode	call.

RETURN VALUE
       Returns 0 on success, or	-1 on error.

EXAMPLE
       SDL_GL_SetAttribute( SDL_GL_RED_SIZE, 5 );
       SDL_GL_SetAttribute( SDL_GL_GREEN_SIZE, 5 );
       SDL_GL_SetAttribute( SDL_GL_BLUE_SIZE, 5	);
       SDL_GL_SetAttribute( SDL_GL_DEPTH_SIZE, 16 );
       SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 );
       if ( (screen=SDL_SetVideoMode( 640, 480,	16, SDL_OPENGL )) == NULL ) {
	 fprintf(stderr, "Couldn't set GL mode:	%s
       ", SDL_GetError());
	 SDL_Quit();
	 return;
       }

	      Note:

	      The  SDL_DOUBLEBUF flag is not required to enable	double buffer-
	      ing when setting an OpenGL video mode. Double buffering  is  en-
	      abled or disabled	using the SDL_GL_DOUBLEBUFFER attribute.
