threading

Hi, If I want to achieve some simultaneous activity through C programming....... say I just want to display the clock in seconds at the bottom of the page while some activity is going on on the page....... how do I achieve it by C ? After all, even Jave in its initial days was developed by C...

i wanna know if is there a processor P4 which is dual core and has hyper threading features

In my recently posted queries, one of the moderators stated that the prescott processesor had Hyper threading tech. is it true ????????
