MPI_Comm_get_errhandler(3)         Open MPI         MPI_Comm_get_errhandler(3)



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.
