[][src]Function spatialite_sys::gaiaGeomCollCentroid_r

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

Spatial operator: Centroid

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom pointer to Geometry object. \param x on completion this variable will contain the centroid X coordinate \param y on completion this variable will contain the centroid Y coordinate

\return 0 on failure: any other value on success

\sa gaiaGeomCollCentroid, gaiaRingCentroid

\note reentrant and thread-safe.

\remark \b GEOS support required.
