       int
       thrd_join(thrd_t thrd, int *res);
  
  DESCRIPTION
!      The thrd_join() function suspends the exection of the current thread and
       waits for the thread indicated by thrd to terminate and stores the exit
       status, as set by a call to thrd_exit(3C), for that thread in res, if res
       is non-null.  The thrd argument must be a member of the current process
       and it cannot be detached.  If thrd has already terminated and another
       caller has not called thrd_join() then the exit status will be returned

! RETURN_VALUES
       Upon successful completion, the thrd_join() function returns thrd_success
       and if res is a non-null pointer, it will be filled in with the exit
       status of thrd.  If an error occurs, thrd_error will be returned.
