Function spatialite_sys::gaiaLineMerge_r

pub unsafe extern "C" fn gaiaLineMerge_r(
    p_cache: *const c_void, 
    geom: gaiaGeomCollPtr
) -> gaiaGeomCollPtr

Spatial operator: Line Merge

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom pointer to input Geometry object.

\return the pointer to newly created Geometry object; NULL on failure. \n if possible, this representing a reassembled Linestring or MultiLinestring.

\sa gaiaLineMerge, gaiaFreeGeomColl

\note you are responsible to destroy (before or after) any allocated Geometry, this including any Geometry returned by gaiaLineMerge_r()\n reentrant and thread-safe.

\remark \b GEOS-ADVANCED support required.
