[antlr-interest] How to use ANTLR to find function pointers

[amol Bhagavat]

Ok if i get a proper c grammer, i can easily find out function pointers in that ...
  Is it possible to find the different assignments done to function pointers in source code?

At first, I would recommend to buy the ANTLR book
. It is really
helpful, especially, because it contains an example, on which you can
build upon. Alternatively you can look at the source code of the CMinus
example on the same website. That's for understanding only. You'd need a
C grammar, too. Maybe it has been posted one on the grammar site
(somewhere on antlr.org).

On your special I would then generate an AST containing only the
functions and function pointers and then a tree grammar, which can
output the required information. Sorry I can't be more specific at this
stage!
