/*@
   MPI_Win_get_info - Returns a new info object containing the hints of the
   window associated with win. The current setting of all hints actually used
   by the system related to this window is returned in info_used. If no such
   hints exist, a handle to a newly created info object is returned that
   contains no key/value pair. The user is responsible for freeing info_used
   via MPI_INFO_FREE.

   Input Parameters:
. win - window object (handle)

   Output Parameters:
. info - new info argument (handle)

.N Fortran
