[cfe-dev] NestedNameSpecifier-equivalent for CallExpr?

[Jordan Rose]

Hi, Lukhnos. You can get the function/method/whatever being called using CallExpr::getCallee, and from there you should be able to pick it apart if it's a DeclRefExpr. (Note that a callee could easily /not/ be a DeclRefExpr, say if it's a lambda expression.)

Is that what you're looking for?

But for the former, I'm interested in the exact location of the identifier "foo" (the other info I can get from getDirectCallee()). I can't figure out a way to do it other than parsing the range between the start loc and the left parenthesis. Or did I miss anything?
