[postgis-devel] Can I call LWGEOM_x_point directly from another stored procedure?

[Stephen Woodbridge]

Hi strk,

I would like to be able to pass a PostGIS point or point[] to a 
pgRouting function and I'm wondering if is it is possible to directly 
call LWGEOM_x_point() and somehow pass on of my args to that?

Basically, I would like a simple way to get x, y, and srid from a point. 
I guess I can clone the code from LWGEOM_x_point into a function to 
extract those.

Do I need to do anything to initialize stuff for postgis in my function?

Thanks,
   -Steve
