NAME
     thrd_join – detach thread

SYNOPSIS
     library “threads”
     #include <threads.h>

     int
     thrd_join(thrd_t thrd, int *res);

DESCRIPTION
     The function thrd_join() will suspend the execution of the current thread
     and will wait for the given thread thrd to finish executing. The exit
     status of the given thread as set by thrd_exit(3) can then be retrieved
     by the res argument if it is not NULL.

     The given thread must not have been detached by thrd_detach(3) and must
     be a member of the current process.

     If the given thread has already been terminated and thrd_join() has not
     yet been called for the given thread before, the exit status can be
     retrieved without the function blocking.

     If multiple threads call thrd_join() for the same thread they all will
     wait for execution of the given thread, however only one of the threads
     will retrieve the exit status.

RETURN VALUES
     The function thrd_join() returns thrd_success on success. If the res
     argument is not NULL it will populate the integer pointed to by the
     argument with the exit status of the joining thread.  In case of an error
     thrd_error if an error has occurred.
