MPI_Comm_get_errhandler(3OpenMPI)                                          MPI_Comm_get_errhandler(3OpenMPI)



NAME
       MPI_Comm_get_errhandler  - Retrieves error handler associated with a communicator.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Comm_get_errhandler(MPI_Comm comm,
            MPI_Errhandler *errhandler)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_GET_ERRHANDLER(COMM, ERRHANDLER, IERROR)
            INTEGER   COMM, ERRHANDLER, IERROR


C++ Syntax
       #include <mpi.h>
       MPI::Errhandler MPI::Comm::Get_errhandler() const


INPUT PARAMETER
       comm      Communicator (handle).


OUTPUT PARAMETERS
       errhandler
                 New error handler for communicator (handle).

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Comm_get_errhandler  retrieves  the  error handler currently associated with a communicator. This
       call is identical to MPI_Errhandler_get, the use of which is deprecated.


ERRORS
       Almost all MPI routines return an error value; C routines as the value of the  function  and  Fortran
       routines  in  the  last argument. C++ functions do not return errors. If the default error handler is
       set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to  throw
       an MPI:Exception object.

       Before  the  error value is returned, the current MPI error handler is called. By default, this error
       handler aborts the MPI job, except for I/O function errors. The error handler  may  be  changed  with
       MPI_Comm_set_errhandler;  the  predefined  error handler MPI_ERRORS_RETURN may be used to cause error
       values to be returned. Note that MPI does not guarantee that an MPI  program  can  continue  past  an
       error.

       See the MPI man page for a full list of MPI error codes.
