Date: Sat, 2 Aug 2003 16:22:51 +0300 From: "Mike Gorchak" Subject: New patches for QNX6 Here my patches for the SDL/QNX: QNXSDL.diff - diff to non-QNX related sources: - updated BUGS file, I think QNX6 is now will be officially supported - configure.in - added shared library support for QNX, and removed dependency between the ALSA and QNX6. - SDL_audio.c - added QNX NTO sound bootstrap insted of ALSA's. - SDL_sysaudio.h - the same. - SDL_nto_audio.c - the same. - SDL_video.c - right now, QNX doesn't offer any method to obtain pointers to the OpenGL functions by function name, so they must be hardcoded in library, otherwise OpenGL will not be supported. - testsprite.c - fixed: do not draw vertical red line if we are in non-double-buffered mode. sdlqnxph.tar.gz - archive of the ./src/video/photon/* . Too many changes in code to make diffs :) : + Added stub for support hide/unhide window event + Added full YUV overlays support. + Added window maximize support. + Added mouse wheel events. + Added support for some specific key codes in Unicode mode (like ESC). + Added more checks to the all memory allocation code. + Added SDL_DOUBLEBUF support in all fullscreen modes. + Added fallback to window mode, if desired fullscreen mode is not supported. + Added stub support for the GL_LoadLibrary and GL_GetProcAddress functions. + Added resizable window support without caption. ! Fixed bug in the Ph_EV_EXPOSE event handler, when rectangles to update is 0 and when width or height of the rectangle is 0. ! Fixed bug in the event handler code. Events has not been passed to the window widget handler. ! Fixed codes for Win keys (Super/Hyper/Menu). ! Fixed memory leak, when deallocation palette. ! Fixed palette emulation code bugs. ! Fixed fullscreen and hwsurface handling. ! Fixed CLOSE button bug. First event was passed to the handler, but second terminated the application. Now all events passed to the application correctly. - Removed all printfs in code, now SDL_SetError used instead of them. - Disabled ToggleFullScreen function. README.QNX - updated README.QNX file. Added much more issues.

.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"
