hi,
it does not matter, if definitions change, as long as you are using obj_noutlets() and obj_{start,next}traverseoutlet() -- take a look at my example (it is cluttered somewhat with the viral code, sorry)...

thanks very much for all your help. I realized that i can use the _outlet and _outconnect structures to get the successors of an object. As the struct definitions are hidden in a *.c-file and not publicly declared in a header file: can they be subject to severe changes in a future version of pd?
