I have a question about the function sleep();. I need to know what exactly it does. Does it just freeze the computer for a certain time? Or are you allowed to do stuff while it is sleeping? Ex. What I want to do is use sleep(); to put a time constraint on the user. But still allow the user to go about the screen. But when the time is up it goes to another function. Could this be done?

The windows version of Sleep simply freezes the thread that enters the function. Other running threads arent affected
Short Answer, it pauses the thread for the number of milliseconds,
that you choose.
If you do not put your interface on a separate thread, then it will 'freeze' until the Sleep has expired.

It is not that old programmers are any smarter or code better, it is just that they have made the same stupid mistake so many times that it is second nature to fix it.

Be careful calling Sleep() within Windows programs, especially those that are call Sleep() from the same thread as the message handler for the user interface. If your program does not check for messages for 5 seconds, Windows will decide it is unresponsive, so Sleep() can be dangerous. It's probably better to use SetTimer() if you need to delay for more than a few milliseconds.
Away.
