Hi,
Thanks for your input. But my requirement is little bit different.

Pls help me...

rfork_thread
RFORK_THREAD(3) BSD Library Functions Manual RFORK_THREAD(3)
NAME
rfork_thread -- create a rfork-based process thread
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
pid_t
rfork_thread(int flags, void *stack, int (*func)(void *arg), void *arg);
DESCRIPTION
The rfork_thread() function has been deprecated in favor of pthread_create(3).
The rfork_thread() function is a helper function for rfork(2). It arranges for a new process to be created and the child process will call
the specified function with the specified argument, while running on the supplied stack.
Using this function should avoid the need to implement complex stack swap code.
RETURN VALUES
Upon successful completion, rfork_thread() returns the process ID of the child process to the parent process. Otherwise, a value of -1 is
returned to the parent process, no child process is created, and the global variable errno is set to indicate the error.
The child process context is not aware of a return from the rfork_thread() function as it begins executing directly with the supplied func-
tion.
ERRORS
See rfork(2) for error return codes.
SEE ALSO
fork(2), intro(2), minherit(2), rfork(2), vfork(2), pthread_create(3)
HISTORY
The rfork_thread() function first appeared in FreeBSD 4.3.
