NAME

       MPI_Errhandler_get  - Gets the error handler for a communicator -- use of this routine is deprecated.

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Errhandler_get(MPI_Comm comm, MPI_Errhandler *errhandler)

Fortran Syntax

       INCLUDE 'mpif.h'
       MPI_ERRHANDLER_GET(COMM, ERRHANDLER, IERROR)
            INTEGER   COMM, ERRHANDLER, IERROR

INPUT PARAMETER

       comm      Communicator to get the error handler from (handle).

OUTPUT PARAMETERS

       errhandler
                 MPI error handler currently associated with communicator (handle).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       Note that use of this routine is deprecated as of MPI-2. Please use MPI_Comm_get_errhandler instead.

       This deprecated routine is not available in C++.

       Returns  in  errhandler  (a  handle  to) the error handler that is currently associated with communicator
       comm.

       Example: A library function may register at its entry point the current error handler for a communicator,
       set  its  own  private error handler for this communicator, and restore before exiting the previous error
       handler.

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.
