:ref:`MPI_Comm_set_errhandler` |mdash| Attaches a new error handler to a communicator.

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Comm_set_errhandler(MPI_Comm comm,
     MPI_Errhandler errhandler)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_COMM_SET_ERRHANDLER(COMM, ERRHANDLER, IERROR)
     INTEGER COMM, ERRHANDLER, IERROR

Fortran 2008 Syntax

USE mpi_f08
MPI_Comm_set_errhandler(comm, errhandler, ierror)
     TYPE(MPI_Comm), INTENT(IN) :: comm
     TYPE(MPI_Errhandler), INTENT(IN) :: errhandler
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

INPUT/OUTPUT PARAMETER

  • comm: Communicator (handle).

OUTPUT PARAMETERS

  • errhandler: New error handler for communicator (handle).
  • ierror: Fortran only: Error status (integer).

DESCRIPTION

:ref:`MPI_Comm_set_errhandler` attaches a new error handler to a communicator. The error handler must be either a predefined error handler or an error handler created by a call to :ref:`MPI_Comm_create_errhandler`. This call is identical to :ref:`MPI_Errhandler_set`, the use of which is deprecated.
