ESMF_XGridGetGB Subroutine

subroutine ESMF_XGridGetGB(xgrid, sideA, sideB, rc) 

!
! !ARGUMENTS:
type(ESMF_XGrid), intent(in)                :: xgrid
type(ESMF_XGridGeomBase), intent(out)       :: sideA(:), sideB(:)
integer, intent(out), optional              :: rc 
!
! !DESCRIPTION:
!      Get information about XGrid
!
!     The arguments are:
!     \begin{description}
!     \item [xgrid]
!       The {\tt ESMF\_XGrid} object used to retrieve information from.
!     \item [{[sideA]}]
!           2D GeomBase objects on side A
!     \item [{[sideB]}]
!           2D GeomBase objects on side B
!     \item [{[rc]}]
!           Return code; equals {\tt ESMF\_SUCCESS} only if the {\tt ESMF\_XGrid} 
!           is created.
!     \end{description}
