SDL_SetVideoMode(3)			SDL API Reference		      SDL_SetVideoMode(3)

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

       #include "SDL.h"

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

       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 com-
       binations 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 updates of the display  surface.  This
			   will  usually  slow down blitting on single CPU machines, but may pro-
			   vide a speed increase on SMP systems.

       SDL_ANYFORMAT	   Normally, if a video surface of the requested bits-per-pixel (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 pixel depth.

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

       SDL_DOUBLEBUF	   Enable hardware double buffering; only valid with SDL_HWSURFACE. Call-
			   ing SDL_Flip will flip the buffers and update the screen. All  drawing
			   will take place on the surface that is not displayed at the moment. 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. If a hardware resolution
			   change is not possible (for whatever reason), the next higher  resolu-
			   tion  will  be  used  and the display window centered on a black back-

       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 blit-
			   ting operations. The screen (2D) surface may have  an  alpha  channel,
			   and	SDL_UpdateRects  must  be used for updating changes to the screen

       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


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


	      The  bpp	parameter is the number of bits per pixel, so a bpp of 24 uses the packed
	      representation of 3 bytes/pixel. For the more common 4 bytes/pixel mode, use a  bpp
	      of  32.  Somewhat oddly, both 15 and 16 will request a 2 bytes/pixel mode, but dif-
	      ferent pixel formats.

       The framebuffer surface, or NULL if it fails. The surface returned is freed by  SDL_Quit()
       and should nt be freed by the caller.
