NAME

SDL_GL_SetAttribute?- Set a special SDL/OpenGL attribute

SYNOPSIS

#include

int SDL_GL_SetAttribute?(SDL_GLattr attr, int value);

RETURN VALUE

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,

Note:

The SDL_DOUBLEBUF flag 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.
