#include <pthread.h>
int
pthread_join
(pthread_t
thread, void
**value_ptr);
pthread_join
() function suspends execution of the
calling thread until the target thread terminates unless
the target thread has already terminated.
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
_POSIX_THREAD_THREADS_MAX
.
pthread_join
() function will return
zero. Otherwise an error number will be returned to indicate the error.
pthread_join
() shall fail if:
EINVAL
]ESRCH
]pthread_join
() may fail if:
EDEADLK
