MPI_Win_get_group(3)               Open MPI               MPI_Win_get_group(3)



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++
       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.
