I don't think Microwindows provides for anything like this. Are you
running Linux (unix)? If so, you can use signal() and alarm() for low
resolution timers. select() and setitimer() can be used for higher
resolutions.

See the man pages for the above functions.
Normally, you set up a signal handler for the SIGALRM and use alarm to
start timers.
main()
{
signal(SIGLARM,sigalrm);
alarm(5);
for(;;);
}
void
sigalrm(int signo)
{
printf("signal from alarm\n");
}
The above timer will pop in 5 seconds.
Later, Kyle.
