C++ newbie help! need help with timer/counter?

[m_s2k7]

I need help finding an FLTK function that counts down in the background.

I remember skimming across a function using FLTK that pretty much took in an int, and ran a counter in the background of the program for as many seconds as the int specified. But now I cannot find it and I can't remember for the life of me what it was called exactly.

Any one have any idea on what the function is or any other way to implement this task even outside of FLTK?
