I pointed out that qsort() and bsearch() are good simple examples of how
callbacks are used, and I recommended searching
Wikipedia.<http://en.wikipedia.org/wiki/Callback_%28computer_programming%29>
has two completely filled out toy examples of code using callback
functions. Joe Pfeiffer pointed you at a tutorial for FUSE, which is a
more complicated system making use of callbacks. Les Cargill gave you a
basic template for implementing callbacks in C.

Callback are a relatively simple concept. Everything that makes a
callback be a callback is present in both Wikipedia's examples and in
Les Cargill's template. If there's something more that you need, that
wasn't provided by those examples, then you're looking for something
more than just a callback. Perhaps you could explain in more detail what
you're looking for that was missing from these examples?
