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++ func-
       tions  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.
