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_SetTimer\- Set a callback to run after the specified number of milliseconds has elapsed\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_SetTimer\fP\fR(\fBUint32 interval, SDL_TimerCallback callback\fR);
.SH "CALLBACK"
.PP
/* Function prototype for the timer callback function */ typedef Uint32 (*SDL_TimerCallback)(Uint32 interval);
.SH "DESCRIPTION"
.PP
Set a callback to run after the specified number of milliseconds has elapsed\&. The callback function is passed the current timer interval and returns the next timer interval\&. If the returned value is the same as the one passed in, the periodic alarm continues, otherwise a new alarm is scheduled\&.
.PP
To cancel a currently running timer, call \fBSDL_SetTimer(0, NULL);\fP
.PP
The timer callback function may run in a different thread than your main constant, and so shouldn\&'t call any functions from within itself\&.
.PP
The maximum resolution of this timer is 10 ms, which means that if you request a 16 ms timer, your callback will run approximately 20 ms later on an unloaded system\&. If you wanted to set a flag signaling a frame update at 30 frames per second (every 33 ms), you might set a timer for 30 ms (see example below)\&.
.PP
If you use this function, you need to pass \fBSDL_INIT_TIMER\fP to \fBSDL_Init()\fP\&.
.PP
.RS
\fBNote:  
.PP
This function is kept for compatibility but has been superseded by the new timer functions \fISDL_AddTimer\fR and \fISDL_RemoveTimer\fR which support multiple timers\&.
