MPI_Session_create_errhandler

:ref:`MPI_Session_create_errhandler` - Creates an error handler that can be attached to sessions

SYNTAX

C Syntax

#include <mpi.h>

int MPI_Session_create_errhandler(MPI_Session_errhandler_function *function,
    MPI_Errhandler *errhandler)

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_SESSION_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR)
    EXTERNAL    FUNCTION
    INTEGER ERRHANDLER, IERROR

Fortran 2008 Syntax

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

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:

SUBROUTINE SESSION_ERRHANDLER_FUNCTION(SESSION, ERROR_CODE, ...)
   INTEGER SESSION, ERROR_CODE
