NAMEpthread_join — wait for thread termination
LIBRARYPOSIX Threads Library (libpthread, -lpthread)
pthread_join(pthread_t thread, void **value_ptr);
DESCRIPTIONThe 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.
RETURN VALUESIf successful, the pthread_join() function will return zero. Otherwise an error number will be returned to indicate the error.
ERRORSpthread_join() shall fail if:
- The value specified by thread does not refer to a joinable thread.
- No thread could be found corresponding to that specified by the given thread ID, thread.
pthread_join() may fail if:
- A deadlock was detected or the value of thread specifies the calling thread.
STANDARDSThe function conforms to IEEE Std 1003.1-2001 (“POSIX.1”).
