Just to make sure I understand your approach correctly: After the script
is loaded, check if there is a global function called, for example,
"cb_read". If there is, call it every $interval seconds. The script does
not call any register_* function for this to happen – defining the
function with this special name is sufficient.

I think providing the register_* functions is worth the trouble: It is
closer to the C API and the interfaces provided by the Perl and Python
plugins. The Java API is a bit special because Java doesn't provide
function pointers, but you can still register objects implementing a
special interface.

Oh, sorry about that :/ I didn't mean to "steal" your plugin, I just got
excited and carried away. When I get excited about something I usually
start hacking away in a frenzy, sorry … I'll hold myself back.

No offense taken.

Oh $deity! The pkg-config names are the one thing that should be
constant over all platforms … Oh well, I'll see if I can work around
that.
