You meet to use multithreading for this. Do a Google search for C++ threading tutorial, and you'll find lots of help on how to do this.

I'm not sure OP has convinced me that multithreading is the answer he needs.

The system clock runs regardless of what your program does.
If all you want to do is see how long something takes then just look at the clock every now and then.
