MPI_Errhandler_get

Syntax:

MPI_Errhandler_get( comm, errhandler )

comm - Kommunikator (handle)

errhandler - Errorhandler (handle)

#include "mpi.h"

int my_function(MPI_Comm comm) { 

    int                    msg, myid;
    MPI_Errhandler         errh, store_errh;

    ...
    /* alten Errorhandler merken */
    MPI_Errhandler_get(comm, &store_errh);

    MPI_Errhandler_create((MPI_Handler_function *)(&my_errhandler), &errh);
    MPI_Errhandler_set(comm, errh);
    ...
    MPI_Errhandler_free(&errh);
    /* Errorhandler wieder setzen */
    MPI_Errhandler_set( comm, store_errh);
}
