[cdt-dev] How do I get the member declaration for a member function call

[Jeff Johnston <jjohnstn@xxxxxxxxxx>]

I have a C++ file and in it I have:

  std::string *k = new std::string("blah");
  k->append(3, 'c');

I have the file position of the append call.  Is there a way I can find 
the declaration of the append member function for std::string (which is 
actually std::basic_string<char>) from the AST?  Doing a dump of the AST 
via ASTPrinter, the information appears to be there.  I am trying to 
narrow down which append() method is being called as there are multiple 
versions for std::basic_string<char>.

FWIW: I was able to locate the IASTName for the append call using the 
IASTNodeSelector and when I tried to use its binding and called 
getDeclarationsInAST(), I ended up with an empty list.

Thanks in advance,
