How to sleep in kernel ?

[bsd_newbie]

I'd like to put a delay for 1 second in my driver somewhere. What is the bsd function to do that. Basically this is for debugging only as I want printfs to be printed out slowly...

I am thinking of putting DELAY(1000000), let me know if that makes sense.
-thanks in advance.

Delay is fine, but seems it is a busy loop. What I want is a 1 second cpu relinquishable sleep.

thanks.
