[−][src]Function spatialite_sys::gaiaCloneRingSpecial
pub unsafe extern "C" fn gaiaCloneRingSpecial(
ring: gaiaRingPtr,
mode: c_int
) -> gaiaRingPtr
Duplicates a Ring object (special)
\param ring pointer to Ring object [origin]. \param mode one of GAIA_SAME_ORDER or GAIA_REVERSE_ORDER.
\return the pointer to newly created Ring object: NULL on failure.
\sa gaiaCloneRing, gaiaClonePolygonSpecial
\note if GAIA_REVERSE_ORDER is specified, then any vertex into the newly created object will be in reverse order [first vertex will be last one, and last vertex will be the first one]. In any other case this function will simply default to gaiaCloneRing.
