How to show function prototype in Emacs?
c, emacs, etag
Solution
c-eldoc-mode is a mode that is not as heavyweight as CEDET that will do precisely what you want.
Problem
While in C-mode I can jump to a function using M-. on the function name....is there a way i can simply display the function prototype? (preferably as a tooltip or so) I often struggle to remember the exact order and types required by a given function.
