pthread_join -- wait for thread termination

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 tar-
get thread are undefined. If the thread calling pthread_join() is can-
celled, 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.
The pthread_join() function will fail if:
[EINVAL] The implementation has detected that the value speci-
fied by thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to that speci-
fied by the given thread ID, thread.
[EDEADLK] A deadlock was detected or the value of thread speci-
fies the calling thread.
The pthread_join() function conforms to ISO/IEC 9945-1:1996
