NAME
       MPI_Comm_remote_group  - Accesses the remote group associated with an intercommunicator.

SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Comm_remote_group(MPI_Comm comm, MPI_Group *group)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_COMM_REMOTE_GROUP(COMM, GROUP, IERROR)
	    INTEGER   COMM, GROUP, IERROR

C++ Syntax
       #include <mpi.h>
       Group Intercomm::Get_remote_group() const

INPUT PARAMETER
       comm	 Communicator.

OUTPUT PARAMETERS
       group	 Remote group of communicator.

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       MPI_Comm_remote_group accesses the remote group associated with an intercommunicator.

       The intercommunicator accessors (MPI_Comm_test_inter, MPI_Comm_remote_size, MPI_Comm_remote_group) are all local operations.

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.
