I just realized I should be posting in the pd-dev list so from now on any questions I have relating to this project will be posted there.
Martin, I am getting a weird error when I try sym = gensym(symstr); I get no match for 'operator=' in 'sym = gensym(((char*)(& symstr)))' I dont know what thats all about. I have seen this used before with no problems.

You could convert the pointer to a float but it probably won't work because the pointer is a large integer that won't be accurately represented as a float. You could convert the pointer to a symbol using something like: > char symstr[10]; > t_symbol sym; > sprintf(symstr, "%p", frame); > sym = gensym(symstr); > ...then send sym through the outlet and convert it back to a pointer at the > receiving end by extracting the string from the s_name field of the symbol and passing it to atol(). > > Martin > _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
