And what code do you use to parse this?

That's what you get by default if you match for e.g. functionDecl() and
have a callback like this:

----
class Callback : public clang::ast_matchers::MatchFinder::MatchCallback
{
  public:
    Callback() {}

    void
    run(const clang::ast_matchers::MatchFinder::MatchResult& result) override
    {
        const auto decl = result.Nodes.getNodeAs<clang::FunctionDecl>("decl");
        if (!decl)
        {
            return;
        }

        std::cerr << decl->parameters()[0]->getType().getAsString() << std::endl;
    }
};
----

This prints "my_int_t" for me with your above 2 liner input.

Regards,

Miklos
