- * DOCPUBLIC
- * This function waits for 'thread' to terminate and
- * returns the thread's exit value if 'value_ptr' is not
- * NULL. This also detaches the thread on successful
- * completion.
- *
- * PARAMETERS
- * thread
- * an instance of pthread_t
- *
- * value_ptr
- * pointer to an instance of pointer to void
- *
- *
- * DESCRIPTION
- * This function waits for 'thread' to terminate and
- * returns the thread's exit value if 'value_ptr' is not
- * NULL. This also detaches the thread on successful
- * completion.
- * NOTE: detached threads cannot be joined or canceled
- *
- * RESULTS
- * 0 'thread' has completed
- * EINVAL thread is not a joinable thread,
- * ESRCH no thread could be found with ID 'thread',
- * ENOENT thread couldn't find it's own valid handle,
- * EDEADLK attempt to join thread with self
- *
