libclang is the easiest way to get this information; check out http://clang.llvm.org/doxygen/group__CINDEX.html

You can also get it by adding your own ASTConsumer and looking at the contents of each VarDecl that it sees. That's more involved, though.

It's an option meant only for debugging, so the format may change from time to time.

Most, but not all, because it's a debug option.
