pthread_join -- wait for thread termination
POSIX Threads Library (libpthread, -lpthread)
pthread_join(pthread_t thread, void **value_ptr);
The pthread_join() function suspends execution of the calling thread
until the target thread terminates unless the target thread has already
On return from a successful pthread_join() call with a non-NULL value_ptr
argument, the value passed to pthread_exit() by the terminating thread is
stored in the location referenced by value_ptr. When a pthread_join()
returns successfully, the target thread has been terminated. The results
of multiple simultaneous calls to pthread_join() specifying the same
target thread are undefined. If the thread calling pthread_join() is
cancelled, then the target thread is not detached.
A thread that has exited but remains unjoined counts against
If successful, the pthread_join() function will return zero. Otherwise
an error number will be returned to indicate the error.
pthread_join() shall fail if:
[EINVAL] The value specified by thread does not refer to a
[ESRCH] No thread could be found corresponding to that
specified by the given thread ID, thread.
pthread_join() may fail if:
[EDEADLK] A deadlock was detected or the value of thread
specifies the calling thread.
The function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
