[cfe-dev] Accessing c++11 in class initializer AST nodes from lib clang

[mobi phil]

There is a libclang that is a C interface to the full clang and the
full clang lib. Which one are you intending to use?

Without giving you a precise answer, kind of advice from my experince:
print the ast with -dump-ast, see the type of node, and try to
identify functions that brings you from FieldDecl to the initialiazer.

I tried to identify such methods in my tool, it may help you:
