You might have noticed that all the callback takes is a pointer.  Well,
that could be a pointer to anything.  Say, a pointer to a struct, which
contains as many pieces of data as you'd like.

In other words, there is no sense in allowing callbacks to take two
pointers for data, since one can just pass a pointer to any home-grown
data structure containing all the information one needs.

Don't really understand this question.  Can you be a little clearer?
