lwgeom_release()

void lwgeom_release ( LWGEOM *  lwgeom )

extern

Free the containing LWGEOM and the associated BOX.

Leave the underlying geoms/points/point objects intact. Useful for functions that are stripping out subcomponents of complex objects, or building up new temporary objects on top of subcomponents.
