where's the sleep() func?

[TheKedge]

another easy question:

I need a simple delay/sleep in a loop - how do I do it? without getting into threading.

for(int i=0; i<4; ++i)
{
//do something with data[i]
sleep(50);//for example
}

for(int i=0; i<4; ++i)
{
//do something with data[i]
sleep(50);//for example
}

To copy to clipboard, switch view to plain text mode 

a very silly example I know ... but using this could save me making 4 timers.
and yes, generally, it must be a bad idea to put sleep()s into the main thread... but still, it could be handy.

thanks
