Can Emacs show me where a specific function is called?

Question

Is there a way in Emacs to find out which other places in the code call a specific function? With my current setup (GNU emacs 23.1.1, C codebase), I normally have to search the whole codebase for the function name to see which other functions call it. It would be nice if I could efficiently display all the names of the functions that call this specific function that I'm looking at.

You can use semantic-symref function (C-c , G) from CEDET package. It can use GNU Global or CTags databases to find callers if they exist. It could also parse sources to find occurrences.
