+
+INPUT PARAMETER
+---------------
+* ``count``: List length (non-negative integer)
+* ``array_of_requests``: Array of requests (array of handles).
+
+OUTPUT PARAMETERS
+-----------------
+* ``flag``: Boolean flag, same as from :ref:`MPI_Test` (logical).
+* ``array_of_statuses``: Array of ``MPI_Status`` objects if flag is true (array of status).
+* ``ierror``: Fortran only: Error status (integer).
+
+DESCRIPTION
+-----------
+
+:ref:`MPI_Request_get_status_all` sets ``flag = true`` if all
+operations associated with *active* handles in the array have completed.
+In this case, each status entry that corresponds to an active request
+is set to the status of the corresponding operation. It
+does not deallocate or deactivate the request; a subsequent call to
+any of the MPI test, wait, or free routines should be executed with each
+of those requests.
+
+Each status entry that corresponds to a null or inactive handle is set
+to empty.  Otherwise, ``flag = false`` is returned and the values of the
+status entries are undefined.
+
+If your application does not need to examine the *status* field, you can
+save resources by using the predefined constant ``MPI_STATUSES_IGNORE`` as a
+special value for the ``array_of_statuses`` argument.

+DESCRIPTION
+-----------
+
+:ref:`MPI_Request_get_status_any` sets ``flag = true`` if either one
+of the operations associated with active handles has completed. In
+this case it returns in ``index`` the index of this request in the
+array and the status of the operation in ``status``.  It does not
+deallocate or deactivate the request; a subsequent call to any of the MPI
+test, wait, or free routines should be executed with that request.
+
+If no operation completed, it returns ``flag = false`` and a value of
+``MPI_UNDEFINED`` in ``index``. ``status`` is undefined in this
+scenario.
+
+If ``array_of_requests`` contains no active handles then the call
+returns immediately with ``flag = true``, ``index = MPI_UNDEFINED``,
+and an empty status.

+
+DESCRIPTION
+-----------
+
+:ref:`MPI_Request_get_status_some` returns in outcount the number of
+requests from the list ``array_of_requests`` that have completed. The
+first ``outcount`` locations of the array ``array_of_indices`` and
+``array_of_statuses`` will contain the indices of the operations
+within the array ``array_of_requests`` and the status of these

+one in Fortran. It does not deallocate or deactivate the request; a
+subsequent call to any of the MPI test, wait, or free routines should be
+executed with each completed request.
+
+If no operation in ``array_of_requests`` is complete, it returns
+``outcount = 0``. If all operations in ``array_of_requests`` are either
