SDL_GL_SetAttribute — Set a special SDL/OpenGL attribute
#include "SDL.h"
int
SDL_GL_SetAttribute( |
SDL_GLattr | attr, |
| int | value); |
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.
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_DOUBLEBUFflag is not required to enable double buffering when setting an OpenGL video mode. Double buffering is enabled or disabled using the SDL_GL_DOUBLEBUFFER attribute.
