MPI_Win win,
_Out_ MPI_Group *group
);
Parameters

Remarks
The group is a duplicate of the group from the communicator used to create the MPI window, and should be freed with MPI_Group_free when it is no longer needed. This group can be used to form the group of neighbors for the routines MPI_Win_post and MPI_Win_start.
