Date: Sat, 03 Jul 2004 02:23:48 +0200 From: Marcin Konicki Subject: [PATCH] Add missing functions and bring back OpenGL This patch adds missing functions: IconifyWindow GetWMInfo GL_LoadLibrary GL_GetProcAddress GL_GetAttribute GL_MakeCurrent Adding GL_* functions brings back working OpenGL in SDL for BeOS :). With addd GL_* functions there are few changes in Window class to handle changes better. Patch also fixes bug which freezed window when using MesaGL instead of BeOS r5 GL - it just needed Window->Quit() added into BE_VideoQuit(). THX to Michael Weirauch (a.k.a emwe) who worked on that bug before and found that it freezes because of lock somewhere. THX to Matti "Mictlantecuhtli" Lev��nen for testing, Rod��ric Vicaire (a.k.a. Ingenu) for OpenGL wisdom, and Stefano Ceccherini (a.k.a Jack Burton) for asking me to fix SDL on BeOS :).

.SH "NAME"
SDL_VideoModeOK\- Check to see if a particular video mode is supported\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_VideoModeOK\fP\fR(\fBint width, int height, int bpp, Uint32 flags\fR);
.SH "DESCRIPTION"
.PP
\fBSDL_VideoModeOK\fP returns \fB0\fR if the requested mode is not supported under any bit depth, or returns the bits-per-pixel of the closest available mode with the given width, height and requested \fIsurface\fR flags (see \fI\fBSDL_SetVideoMode\fP\fR)\&.
.PP
The bits-per-pixel value returned is only a suggested mode\&. You can usually request and bpp you want when \fIsetting\fR the video mode and SDL will emulate that color depth with a shadow video surface\&.
.PP
The arguments to \fBSDL_VideoModeOK\fP are the same ones you would pass to \fISDL_SetVideoMode\fR
.SH "EXAMPLE"
.PP

Uint32 bpp;

printf("Checking mode 640x480@16bpp\&.

  printf("Mode not available\&.
");
  exit(-1);
