I think you're better off reading about it in the Elisp manual.
The third argument (called ACTION usually) is basically the *method* to
use on the "object implemented as a function".  It can be nil (which
means `try-completion'), t (which means `all-completions'), lambda
(which means `test-completion'), or `boundaries', or `metadata'.
