Regular expression to match calls (C)

Question

Does anyone have a regex to match function calls in C programs?

Answer 1

After a bit more searching, I decided to give the compiler hard work.

Get a compiler to create a Register Transfer Language (RTL) file using the -dr gcc options.

The resulting RTL file has the suffix .rtl or .expand.

This file is much easier to parse because function calls are already identified.

Answer 2

Since C is not a regular language , and calls to C functions may contain arbitrary argument expressions, I am afraid that the answer to your question will be no.

Answer 3

I doubt that you can find a regular expression that matches all (and only) function calls in some source code. But perhaps you could use a tool like Understand or your IDE to view your code.
