I get this using libclang 3.3 on OS X:

test.cpp:1:6 (5, 0-10) kind: VarDecl type: int display name: i usr: c:@i 
definition
   test.cpp:1:10 (9, 9-10) kind: IntegerLiteral type: int

Of course I forgot to use "clang_getCanonicalType". Here's the same 
example updated to use "clang_getCanonicalType" and a switch statement 
on "type.kind" that I tried to explain:
