SDL_SetVideoMode(3)

NAME
SDL_SetVideoMode- Set up a video mode with the specified width, height and bits-per-pixel.

SYNOPSIS

#include "SDL.h"

SDL_Surface *SDL_SetVideoMode(int width, int height, int bpp, Uint32 flags);

DESCRIPTION

Set up a video mode with the specified width, height and bits-per-pixel.

If bpp is 0, it is treated as the current display bits per pixel.

The flags parameter is the same as the flags field of the SDL_Surface structure. OR'd combinations of the following values are valid.

SDL_SWSURFACE
    Create the video surface in system memory

SDL_HWSURFACE
    Create the video surface in video memory

SDL_ASYNCBLIT
    Enables the use of asynchronous to the display surface. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems.

SDL_ANYFORMAT
    Normally, if a video surface of the requested depth (bpp) is not available, SDL will emulate one with a shadow surface. Passing SDL_ANYFORMAT prevents this and causes SDL to use the video surface, regardless of its depth.

SDL_HWPALETTE
    Give SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_SetColors.

SDL_DOUBLEBUF
    Enable double buffering; only valid with SDL_HWSURFACE. Calling SDL_Flip will flip the buffers and update the screen. If double buffering could not be enabled then SDL_Flip will just perform a SDL_UpdateRect on the entire screen.

SDL_FULLSCREEN
    SDL will attempt to use a fullscreen mode

SDL_OPENGL
    Create an OpenGL rendering context. You should have previously set OpenGL video attributes with SDL_GL_SetAttribute.

SDL_OPENGLBLIT
    Create an OpenGL rendering context, like above, but allow normal blitting operations.

SDL_RESIZABLE
    Create a resizable window. When the window is resized by the user a SDL_VIDEORESIZE event is generated and SDL_SetVideoMode can be called again with the new size.

SDL_NOFRAME
    If possible, SDL_NOFRAME causes SDL to create a window with no title bar or frame decoration. Fullscreen modes automatically have this flag set.

    Note:

    Whatever flags SDL_SetVideoMode could satisfy are set in the flags member of the returned surface.

RETURN VALUE

The framebuffer surface, or NULL if it fails.
