Expand description

Topology check: test if a Geometry covers another one

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom1 pointer to first input Geometry object. \param geom2 pointer to second input Geometry object.

\return 0 if false; any other value if geom1 \e spatially \e covers geom2.

\note reentrant and thead-safe.

\remark \b GEOS-ADVANCED support required.
