pthread_exit -- terminate the calling thread
POSIX Threads Library (libpthread, -lpthread)
The pthread_exit() function terminates the calling thread and makes the
value value_ptr available to any successful join with the terminating
thread. Any cancellation cleanup handlers that have been pushed and are
not yet popped are popped in the reverse order that they were pushed and
then executed. After all cancellation handlers have been executed, if
the thread has any thread-specific data, appropriate destructor functions
are called in an unspecified order. Thread termination does not release
any application visible process resources, including, but not limited to,
mutexes and file descriptors, nor does it perform any process level
cleanup actions, including, but not limited to, calling atexit() routines
that may exist.
An implicit call to pthread_exit() is made when a thread other than the
thread in which main() was first invoked returns from the start routine
that was used to create it. The function's return value serves as the
thread's exit status.
The behavior of pthread_exit() is undefined if called from a cancellation
handler or destructor function that was invoked as the result of an
implicit or explicit call to pthread_exit().
After a thread has terminated, the result of access to local (auto) vari-
ables of the thread is undefined. Thus, references to local variables of
the exiting thread should not be used for the pthread_exit() value_ptr
The process will exit with an exit status of 0 after the last thread has
been terminated. The behavior is as if the implementation called exit()
with a zero argument at thread termination time.
The pthread_exit() function cannot return to its caller.
_exit(2), exit(3), pthread_create(3), pthread_join(3)
The function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
