    length: *mut f64,
) -> c_int
Expand description

Measures the total Length for a Geometry object

\param p_cache a memory pointer returned by spatialite_alloc_connection() \param geom pointer to Geometry object \param length on completion this variable will contain the measured length

\return 0 on failure: any other value on success

\sa gaiaGeomCollLenght, gaiaGeomCollArea, gaiaMeasureLength, gaiaGeomCollLengthOrPerimeter

\note reentrant and thread-safe.

\remark \b GEOS support required.
