Read System Clock in Windows

Hello,

I'm writing a program that requires that I generate random numbers. I'm
using the C rand()function. I want to use the system clock as a seed
for the function. How do I read the system clock in Windows? (Please
state any libraries I'm going to need etc).

Thanks,

Moikel

I can imagine some things you need high resolution timing for, but seeding a RNG isn't one of them -- and if you do need that for some reason, you should probably use your own RNG in the first place, rather than use rand. ...
