Get typedef type and name with libclang?

Question

I can get the name and the type of typedefs if they're anonymous structures and the like, but normal typedefs(eg typedef int size_t) I can only get size_t. How can I get the type "int"?

Answer 1

Almost a year late, but this is the first result that came up when I was searching for this exact question, so here's a hopefully better answer:

In clang-c/Index.h, the function clang_getTypedefDeclUnderlyingType will get the type the typedef was typedef'd from, and clang_getCursorType gets the type it was typedef'd to. To clarify, for the line:

typedef a b;

clang_getTypedefDeclUnderlyingType returns a, and clang_getCursorType returns b (both as a CXType).
