RFORK_THREAD(3)	       FreeBSD 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
     function.

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.

FreeBSD	10.1		       February	6, 2011			  FreeBSD 10.1
