[cdt-core-dev] How to get the function calls from a c/cpp project

[jamsheer pk <pkjams@xxxxxxxxx>]

I am writing a code to parse the c/cpp
project.  I have the c projetc name as ICProject. Now I want to
parse  this project to get all the function calls. But when I am
using the statement 

  List functions = translationUnit.getChildrenOfType(ICElement.C_FUNCTION);
 I am getting all the childrens of type function definitions. Not function call. Can anybody tell me how to get that
