3. Can I pass a pointer to a function and have the C library call it

No. See perlcall for how to do it (it comes with several examples).

Well, the answer really is "Yes. See perlcall for how to do it" :)

You can do anything with XS, but you have to provide enough "glue" so that the code provided by your C library cooperates nice with the rest of perl interfaces.
