+.SH "NAME"
+SDL_AddTimer\- Add a timer which will call a callback after the specified number of milliseconds has elapsed\&.
+.SH "SYNOPSIS"
+.PP
+\fB#include "SDL\&.h"
+.sp
+\fBSDL_TimerID \fBSDL_AddTimer\fP\fR(\fBUint32 interval, SDL_NewTimerCallback callback, void *param\fR);
+.SH "CALLBACK"
+.PP

+\f(CW/* type definition for the "new" timer callback function */
+typedef Uint32 (*SDL_NewTimerCallback)(Uint32 interval, void *param);\fR
+.fi
+.PP
+.SH "DESCRIPTION"
+.PP
+Adds a callback function to be run after the specified number of milliseconds has elapsed\&. The callback function is passed the current timer interval and the user supplied parameter from the \fBSDL_AddTimer\fP call and returns the next timer interval\&. If the returned value from the callback 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 \fISDL_RemoveTimer\fR with the timer ID returned from \fBSDL_AddTimer\fP\&.
+.PP
+The timer callback function may run in a different thread than your main program, 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)\&. If you use this function, you need to pass \fBSDL_INIT_TIMER\fP to \fISDL_Init\fR\&.
+.SH "RETURN VALUE"
+.PP
+Returns an ID value for the added timer or \fBNULL\fR if there was an error\&.
+.SH "EXAMPLES"

+\f(CWmy_timer_id = SDL_AddTimer((33/10)*10, my_callbackfunc, my_callback_param);\fR
