If you create a TAGS file for stuff defined only in C files then
sure.  Vanilla `find-tag' can do that (as well as similar Icicles
commands).

(You could also use `icicle-find-file', matching both the file
name (e.g. .*\.c) and a file-content regexp that matches
Emacs-Lisp function definitions in the C source files.)
