.. _mpi_session_create_errhandler:
MPI_Session_create_errhandler
=============================
.. include_body
:ref:`MPI_Session_create_errhandler` |mdash| Creates an error handler that can be
attached to sessions
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Session_create_errhandler(MPI_Session_errhandler_function *function,
MPI_Errhandler *errhandler)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SESSION_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR)
EXTERNAL FUNCTION
INTEGER ERRHANDLER, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: fortran
USE mpi_f08
MPI_Session_create_errhandler(session_errhandler_fn, errhandler, ierror)
PROCEDURE(MPI_Session_errhandler_function) :: session_errhandler_fn
TYPE(MPI_Errhandler), INTENT(OUT) :: errhandler
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT PARAMETER
---------------
* ``function`` : User-defined error handling procedure (function).
OUTPUT PARAMETERS
-----------------
* ``errhandler`` : MPI error handler (handle).
* ``ierror`` : Fortran only: Error status (integer).
DESCRIPTION
-----------
:ref:`MPI_Session_create_errhandler` creates an error handler that can be
attached to sessions. This ``function`` is identical to
:ref:`MPI_Errhandler_create`, the use of which is deprecated. In C, the
user routine should be a ``function`` of type
``MPI_Session_errhandler_function``, which is defined as
.. code-block:: c
typedef void MPI_Session_errhandler_function(MPI_Session *, int *, ...);
The first argument is the session in use. The second is the error code
to be returned by the MPI routine that raised the error. This typedef
replaces ``MPI_Handler_function``, the use of which is deprecated. In
Fortran, the user routine should be of this form:
.. code-block:: fortran
SUBROUTINE SESSION_ERRHANDLER_FUNCTION(SESSION, ERROR_CODE, ...)
INTEGER SESSION, ERROR_CODE
ERRORS
------
.. include:: ./ERRORS.rst
