How to SLeep/Wait?

[walking]

I need ask a process to wait for a while / sleep for a while, then wake up.
Is there any available sleep/wait function in the kernel? Or, how to implement such
function?

Thanks a lot!

Well is this program going to be running in user space or in kernel space? What language is the program written in?

Thanks for your reply! It is running in the kernel space and the program is written in C.

add

#include <unistd.h>

to the code. then the function is:

unsigned int seconds=3; //substitute 3 for however many seconds you'd like to sleep for
sleep(seconds);
