Function spatialite_sys::gaiaGeomCollArea_r

pub unsafe extern "C" fn gaiaGeomCollArea_r(
    p_cache: *const c_void, 
    geom: gaiaGeomCollPtr, 
    area: *mut f64
) -> c_int

Measures the total Area for a Geometry object

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom pointer to Geometry object \param area on completion this variable will contain the measured area

\return 0 on failure: any other value on success
