[geos-devel] Prepared geometry API

[strk]

While working on a testcase for prepared geometries in GEOS
I've found that the documentation for the "GEOSPrepare" function
doesn't match with actual behaviour:

 /*
  * Argument ownership is taken by prepared geometry
  */
 extern const GEOSPreparedGeometry GEOS_DLL *GEOSPrepare(const GEOSGeometry* g);

Testcase is along these lines:

	GEOSGeometry* g = GEOSGeomFromWKT("POLYGON EMPTY");
	const GEOSPreparedGeometry* pg = GEOSPrepare(g);
	GEOSPreparedGeom_destroy(pg);

	// 'g' leaks w/out the call below
	//GEOSGeom_destroy(g);

So, is it documentation wrong or implementation ?
