I see. In fact I use an OO API, ist's just that the object internally
stores a connection resource (i.e. a struct containing stuff I need)
in a private property.
The first version of the extension was not OO, so it seemed straight
forward just to wrap the connection resource within a class, so that
you don't need to pass it around in userspace all the time.
Extending zend_object to store my data structures sounds as the next I
should take to further "objectify" my extension.

Thanks for the pointers!

Greetings
