Tested the new patch to build with old CodeWarrior and MPW, and it seems it needed some hacks with those old headers... Just in case you want to support the archeological versions - here is a small add-on to the above patch, to fix those... http://www.algonet.se/~afb/SDL-1.2.9-classic.patch I couldn't get the old CW5 projects to build without a few modifications - such as deleting the stray old header in: "CWprojects/Support/Carbon/Include/ConditionalMacros.h" ? But I updated both projects to CW6 too and built for Carbon, and it ran all of the Mac test projects without any problems. The MPW file seems to have compiled, with a small order change. As long as you're still shipping the CWProjects and MPWmake with the download, they should probably be updated/fixed ? (another "solution" would of course be to just delete them) I'll post my new projects along with the new Xcode projects later on, along with XML exports of the various .mcp files. (CW5 builds for Classic / "PPC", and CW6 builds for Carbon) It'll be packaged as a part of the next SpriteWorld X release... http://spriteworldx.sourceforge.net/ [Classic/Carbon/Win/X11] --anders

.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\&.
