I don't think any functions to do that are exported, though
there are functions internal to Xlib that do that (like __X11TransIsLocal).
You could probably use that with some nasty kludges, but generally
I think people just try to see if they can attach or not and
suppy a error handler to trap the failure. Attaching could fail on
a system that didn't have shm support even if you were local so
checking for local isn't foolproof.
