Thanks for the quick response.  I feel fairly thick because I don't
understand how the snippets in the FAQ can apply.  They seem to assume
some knowledge that I don't have.

if these are the signatures:
delegate void SampleCB(Object o);
set_sample_callback(SampleCb? cb=null);

how would I add a user data element such as?
void sample_cb(Object o, void* userdata) {...}
int my_data = 0;
set_sample_callback(the_object, &my_data);

Thanks for the help.
