Function spatialite_sys::gaiaBoundary

pub unsafe extern "C" fn gaiaBoundary(geom: gaiaGeomCollPtr) -> gaiaGeomCollPtr

Spatial operator: Boundary

\param geom the Geometry object to be evaluated

\return the pointer to newly created Geometry object representing the geometry Boundary of the input Geometry: NULL on failure.

\sa gaiaBoudary_r, gaiaFreeGeomColl

\note you are responsible to destroy (before or after) any allocated Geometry, this including any Geometry returned by gaiaBoundary()\n not reentrant and thread unsafe.

\remark \b GEOS support required.
