Regular expression to match (C) function calls

Does anyone have a regular expression for matching function calls in C programs ?

From stackoverflow David

• Since C isn't a regular language and C function calls can contain arbitrary argument expressions, I fear the answer to your question is “no.”

  From Konrad Rudolph

• I doubt you can find a regex that matches all (and only) the function calls in some source code. But maybe you could use a tool like Understand, or your IDE, to browse your code.

  From Xavier Nodet

• After a bit more searching I decided to let the compiler do the hard work.

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

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

  This file is far easier to parse as the functions calls are already identified.
