Returns a handle to the isoline that is placed after the specified isoline in a TIN object.

 HANDLE lcTIN_IsoGetNext (
   HANDLE hTIN,
   HANDLE hIsoline
 );

Parameters
hTIN
  Handle to a TIN object.
hIsoline
  Handle to a TIN isoline.

Return Value
  Handle to the isoline that is placed after hIsoline in isolines list.
If there are no isolines after hIsoline, the function returns NULL.
