.TH "SDL_SetVideoMode" "3" "Sun 10 Jun 2001, 19:42" "SDL" "SDL API Reference" .SH "NAME" SDL_SetVideoMode\- Set up a video mode with the specified width, height and bits-per-pixel\&. .SH "SYNOPSIS" .PP \fB#include "SDL\&.h" .sp \fBSDL_Surface *\fBSDL_SetVideoMode\fP\fR(\fBint width, int height, int bpp, Uint32 flags\fR); .SH "DESCRIPTION" .PP Set up a video mode with the specified width, height and bits-per-pixel\&. .PP If \fBbpp\fR is 0, it is treated as the current display bits per pixel\&. .PP The \fBflags\fR parameter is the same as the \fBflags\fR field of the \fI\fBSDL_Surface\fR\fR structure\&. OR\&'d combinations of the following values are valid\&. .TP 20 \fBSDL_SWSURFACE\fP Create the video surface in system memory .TP 20 \fBSDL_HWSURFACE\fP Create the video surface in video memory .TP 20 \fBSDL_ASYNCBLIT\fP 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\&. .TP 20 \fBSDL_ANYFORMAT\fP Normally, if a video surface of the requested depth (\fBbpp\fR) is not available, SDL will emulate one with a shadow surface\&. Passing \fBSDL_ANYFORMAT\fP prevents this and causes SDL to use the video surface, regardless of its depth\&. .TP 20 \fBSDL_HWPALETTE\fP Give SDL exclusive palette access\&. Without this flag you may not always get the the colors you request with \fI\fBSDL_SetColors\fP\fR\&. .TP 20 \fBSDL_DOUBLEBUF\fP Enable double buffering; only valid with SDL_HWSURFACE\&. Calling \fI\fBSDL_Flip\fP\fR will flip the buffers and update the screen\&. If double buffering could not be enabled then \fBSDL_Flip\fP will just perform a \fI\fBSDL_UpdateRect\fP\fR on the entire screen\&. .TP 20 \fBSDL_FULLSCREEN\fP SDL will attempt to use a fullscreen mode .TP 20 \fBSDL_OPENGL\fP Create an OpenGL rendering context\&. You should have previously set OpenGL video attributes with \fI\fBSDL_GL_SetAttribute\fP\fR\&. .TP 20 \fBSDL_OPENGLBLIT\fP Create an OpenGL rendering context, like above, but allow normal blitting operations\&. .TP 20 \fBSDL_RESIZABLE\fP Create a resizable window\&. When the window is resized by the user a \fI\fBSDL_VIDEORESIZE\fP\fR event is generated and \fBSDL_SetVideoMode\fP can be called again with the new size\&. .TP 20 \fBSDL_NOFRAME\fP If possible, \fBSDL_NOFRAME\fP causes SDL to create a window with no title bar or frame decoration\&. Fullscreen modes automatically have this flag set\&. .PP .RS \fBNote: .PP Whatever \fBflags\fR \fBSDL_SetVideoMode\fP could satisfy are set in the \fBflags\fR member of the returned surface\&. .RE .SH "RETURN VALUE" .PP The framebuffer surface, or \fBNULL\fR if it fails\&. .SH "SEE ALSO" .PP \fI\fBSDL_LockSurface\fP\fR, \fI\fBSDL_SetColors\fP\fR, \fI\fBSDL_Flip\fP\fR, \fI\fBSDL_Surface\fR\fR ...\" created by instant / docbook-to-man, Sun 10 Jun 2001, 19:42
