Handle C++ functions with clang API to insert code

Question

I need to preprocess some C++ files to automatically insert code for testing and profiling, and I need to do it with the clang API.

Answer 1

Are there any settings to switch between C and C++ ?

Finally I found out how to handle this:

I extended from ASTConsumer and RecursiveASTVisitor to traverse the AST and implemented VisitCXXRecordDecl(CXXRecordDecl* D). Then I had to set the LangOptions parameter for the preprocessor, so it parses C++.

langOpts.CPlusPlus = 1;

My fault was to think that it would parse C++ right away, but that was not the case, it parses C as default and so doesn't recognize classes.
