Function spatialite_sys::gaiaConvexHull

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

Spatial operator: ConvexHull

\param geom the input Geometry object

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

\sa gaiaConvexHull_r, gaiaFreeGeomColl

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

\remark \b GEOS support required.
