hi. im trying to design a gui program that will quiz her on math. When she takes the quizzes at school they are timed so i want to include this element into the program. Im not certain how to set up the timer aspect of the program. I've been looking at C/C++ libraries dealing with time to try to get a better idea but haven't had much luck yet. Is there an open source program that anyone knows of that has part of the program end after a timer is up that i could look at the source code to get ideas? any help would be appreciated. thanks in advanced.

SDL has timer functionality included, which you can use.

Don't know how this relates to your GUI code but in C, alarm(2) can be used to interrupt a process and force a read(2) to return EINTR after a specified time. man 2 alarm for details. You'll also have to setup an empty signal handler.

seconds = read clock ()
while count down = read clock() != seconds + time out
accept keyboard input()
break;
