Function spatialite_sys::gaiaZRangeRing

pub unsafe extern "C" fn gaiaZRangeRing(
    rng: gaiaRingPtr, 
    min: *mut f64, 
    max: *mut f64
)

Computes the Z-Range for a Ring object

\param rng pointer to the Ring object \param min on completion this variable will contain the min Z value found \param max on completion this variable will contain the max Z value found

\note if the Ring has XY or XYM dims, the Z-Range is meaningless
