请问：pthread_join有没有非阻塞的调用方式？

#ifdef __USE_GNU
/* Check whether thread TH has terminated.  If yes return the status of
   the thread in *THREAD_RETURN, if THREAD_RETURN is not NULL.  */
extern int pthread_tryjoin_np (pthread_t __th, void **__thread_return) __THROW;

/* Make calling thread wait for termination of the thread TH, but only
   until TIMEOUT.  The exit status of the thread is stored in
   *THREAD_RETURN, if THREAD_RETURN is not NULL.

   This function is a cancellation point and therefore not marked with
   __THROW.  */
extern int pthread_timedjoin_np (pthread_t __th, void **__thread_return,
         __const struct timespec *__abstime);
#endif
