Try the stock speedbar in Emacs, I think it's faster.

? What do you mean?

Don't you mean the referenced .C file?  Normally M-. will take you to
the definition of a function, not it's prototype.

I don't understand, surely the function definition gives much more
information than the prototype?

Probably you could find the prototype by going through all the
occurances of a tag by using tags-apropos.  You might also be able to
modify how etags works by giving it a regexp argument - can any other
poster suggest a suitable one?

You can open a man-page with M-x man function-name
If you're using a system with GNU libraries you probably want to be
reading the info files not the man pages.  To do this, when point is on
a function name type C-h C-i and it will jump to the relevant part of
the Glibc manual.
