Function spatialite_sys::gaiaGetPointOnSurface_r

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

Spatial operator: PointOnSurface

\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 Point X coordinate \param y on completion this variable will contain the Point Y coordinate

\return 0 on failure: any other value on success
