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.
