Sorry, swetha, but this is not the right place. We discuss standard C
here. signal, ualarm, sigemptyset, sigaddset and sigprocmask are not
standard C. You may surprised how little standard C deals with: no
threads, no networking, no graphics...

Your best bet would probably be something like linux.dev.c-programming,
but since I do not subscribe to that group, I may be wrong. Find and
read their FAQ first, if they have one.

comp.programming.threads or comp.unix.programmer might also be good
places to post.

Why the hell you want to overlap the scheduler's job (that, in the
case of Linux, *IS* already preemptive), apart of the senselessness of
the question?

PS: remember that you have to write in vanilla english.
PPS: You are OT.

This is a LINUX programming issue. Standard C does not know about such
functions.

Standard C does not know about such functions. You might ask this in a
linus newdgroup. I think comp.os.linux.answers might be a good place
to start.
