NAME
       MPI_Win_get_group - Returns a duplicate of the group of the communicator used to create the window.

SYNTAX
C Syntax
       #include <mpi.h>
       MPI_Win_get_group(MPI_Win win, MPI_Group *group)

Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_WIN_GET_GROUP(WIN, GROUP, IERROR)
	    INTEGER WIN, GROUP, IERROR

C++ Syntax
       #include <mpi.h>
       MPI::Group MPI::Win::Get_group() const

INPUT PARAMETER
       win	 Window object (handle).

OUTPUT PARAMETERS
       group	 Group of processes that share access to the window (handle).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       MPI_Win_get_group returns a duplicate of the group of the communicator used to create the window associated with win. The group is returned
       in group.

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.
