Threads question

[Adam Williams <awilliam@xxxxxxxxxxxxx>]

I've been using POSIX threads for quite some time, having taught myself 
using "http://centaurus.cs.umass.edu/~wagner/threads_html/tutorial.html". 
 In this tutorial they use a function called pthread_delay_np.  I just 
tried to use it, and it appears that my RH box doesn't have it.  I need 
to make a thread sleep for a given qunatity of time, but a call to sleep 
seems to cause all the threads in the process to sleep.  The only 
reference I can find to pthreads_delay_np as it relates specifically to 
Linux is a VERY old Suse rpm that lists the appropriate man page as a 
provided file.  Anyone know the issue with pthread_delay_np or how to 
accomplish an equivalent?
