If :ref:`PR_JoinThread` is not called on the same thread as +:ref:`PR_CreateThread`, then it is the caller's responsibility to ensure +that :ref:`PR_CreateThread` has completed. + +Several threads cannot wait for the same thread to complete. One of the +calling threads operates successfully, and the others terminate with the +error ``PR_FAILURE``. + +The calling thread is not blocked if the target thread has already +terminated. + +:ref:`PR_JoinThread` is interruptible. |
