extern int lwgeom_getsrid(uchar *serialized);
I'm getting a little turned around with all the different forms I can find
geometries in. What is (uchar *) and how does it relate to PG_LWGEOM, LWGEOM
and friends? Specifically, if I have a (LWGEOM *), how do I get a (uchar *)?
This seems to be the only "accessor" method which doesn't take (LWGEOM *).
