I get the impression GNU Readline supports this kind of thing. Though, I have not used it myself. Here is a C++ example of custom auto complete, which could easily be done in C too. There is also a Python API for readline.

This StackOverflow question gives examples in Python, one of which is ...

import readline
def completer(text, state):
    options = [x in addrs where x.startswith(text)]
    if state < options.length:
        return options[state]
    else
        return None
readline.set_completer(completer)

this article on Bash autocompletion may help. This article also gives examples of programming bash's auto complete feature.
