One way to do that is this: produce a file with a list of all the
functions, and visit it in Emacs.  Then use M-/ or C-M-/ to complete
on function names.  (These two commands look in all buffers, so if the
list of functions is in some buffer, you will get what you want.)

Another way is to generate a tag table for your library (using the
etags program that comes with Emacs), then use "M-x complete-tag" to
complete the name of the function at point, and select one of the
completions from the *Completions* buffer.
