.. _mpi_comm_call_errhandler:
MPI_Comm_call_errhandler
========================
.. include_body
:ref:`MPI_Comm_call_errhandler` |mdash| Passes the supplied error code to the error
handler assigned to a communicator
SYNTAX
------
C Syntax
^^^^^^^^
.. code-block:: c
#include <mpi.h>
int MPI_Comm_call_errhandler(MPI_Comm comm, int errorcode)
Fortran Syntax
^^^^^^^^^^^^^^
.. code-block:: Fortran
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_COMM_CALL_ERRHANDLER(COMM, ERRORCODE, IERROR)
INTEGER COMM, ERRORCODE, IERROR
Fortran 2008 Syntax
^^^^^^^^^^^^^^^^^^^
.. code-block:: Fortran
USE mpi_f08
MPI_Comm_call_errhandler(comm, errorcode, ierror)
TYPE(MPI_Comm), INTENT(IN) :: comm
INTEGER, INTENT(IN) :: errorcode
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
INPUT PARAMETER
---------------
* ``comm`` : communicator with error handler (handle).
* ``errorcode`` : error code (integer).
OUTPUT PARAMETERS
-----------------
* ``ierror`` : Fortran only: Error status (integer).
DESCRIPTION
-----------
This function invokes the error handler assigned to the communicator
comm with the supplied error code errorcode. If the error handler was
successfully called, the process is not aborted, and the error handler
returns, this function returns MPI_SUCCESS.
NOTES
-----
Users should note that the default error handler is
MPI_ERRORS_ARE_FATAL. Thus, calling this function will abort the
processes in comm if the default error handler has not been changed.
ERRORS
