ESMF_XGridDistGridsOnline Subroutine

subroutine ESMF_XGridDistGridsOnline(xgtype, mesh, rc)

!
! !ARGUMENTS:
    type(ESMF_XGridType), intent(inout) :: xgtype
    type(ESMF_Mesh),      intent(inout) :: mesh
    integer, intent(out), optional      :: rc

!
! !DESCRIPTION:
!      Create the distgrids for the {ESMF\_XGridType} object
!
!     The arguments are:
!     \begin{description}
!     \item [xgtype]
!           the {ESMF\_XGridType} object.
!     \item [{[mesh]}]
!           the {ESMF\_Mesh} object.
!     \item [{[rc]}]
!           Return code; equals {\tt ESMF\_SUCCESS} only if successful.
!     \end{description}
