title: Gettin line number of the called function
body: <p>Please let me know if I can do it or not?</p>
  
  <p>I am writing a library that could work to track memory allocation and de-allocation in C++. In short, I am trying to see if my application does not have any memory leaks. This is what I did so far.</p>
  
  <p>Overrode the new and the delete operator and now. Whenever the application uses new, I am planning to store the address and the number of bytes that are allocated in that call. Similarly, when the delete is called on that address, I will remove that from the stored list. Until now its fine. But I want to store the file name and the line number from where the "new" is called. I can do that only in the overridden new. Is there a way to get line number in the overridden function?</p>

  <pre><code>1    int main()
  2    {
  3       // Say, A is a structure
  4        A *a = new A();
  5        return 0;
  6     }
  7    void* operator new( size )
  8    {
  9        //
  10       // store the line number and file name on line 4 ??? Can I do it?
  11       return (malloc(size));
  12   }
