Function spatialite_sys::gaiaOutWktEx

pub unsafe extern "C" fn gaiaOutWktEx(
    out_buf: gaiaOutBufferPtr, 
    geom: gaiaGeomCollPtr, 
    precision: c_int
)

Encodes a Geometry object into WKT notation

\param out_buf pointer to dynamically growing Text buffer \param geom pointer to Geometry object \param precision decimal digits to be used for coordinates

\sa gaiaParseWkt, gaiaOutWktStrict, gaiaParseEWKT, gaiaToEWKT

\note this function will apply 3D WKT encoding as internally intended by SpatiaLite: not necessarily intended by other OGC-like implementations. \n Anyway, 2D WKT is surely standard and safely interoperable.
