Pthread_join Error Code 22


NOTES top After a successful call to pthread_join(), the caller is guaranteed that the target thread has terminated. pthread_tryjoin_np is identical to pthread_join except that it will return immediately with the error EBUSY if the target thread th has not exited. If thread_return is not NULL, the return value of th is stored in the location pointed to by thread_return. You should use the same loop as the first one in all three places. http://vealcine.com/error-code/pthread-join-error-code-35.php

The interaction between pthread_join() and cancellation is well-defined for the following reasons: The pthread_join() function, like all other non-async-cancel-safe functions, can only be called with deferred cancelability type. If multiple threads simultaneously try to join with the same thread, the results are undefined. Cant find the game to this melody. Source EINVAL The th thread has been detached.
