I've already implemented this in my branch at https://github.com/vsajip/clang/
as follows:

int    clang_getFunctionArgumentCount(CXType);
CXType clang_getFunctionArgumentType(CXType, unsigned);

The reasoning for the int return from the former is as an error return of -1 in
case the type passed in is not a function with prototype.

I've also implemented exposing constant arrays (as mentioned on issue 9348) using

int clang_getArraySize(CXType); // returns -1 for invalid type
CXType clang_getArrayElementType(CXType);

as well as exposing the type using a new constant CXType_ConstantArray.

Furthermore, I've implemented accessing EnumConstantDecl values as well as
declaration attributes (such as inline) using a function

int clang_getCursorValue(CXCursor);

Might any of these be of any interest for merging into trunk ... ?
