rfork_thread —
create a rfork-based process thread
Standard C Library (libc, -lc)
#include
<unistd.h>
pid_t
rfork_thread(int
flags, void *stack,
int (*func)(void *arg),
void *arg);
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.
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.
See rfork(2) for error return codes.
fork(2), intro(2), minherit(2), rfork(2), vfork(2), pthread_create(3)
The rfork_thread() function first appeared
in FreeBSD 4.3.
