hmm yes you're right, that function doesn't get the pointer type of the 
variable.
Especially for the scoped variables there's no support to include the 
pointer type. The static scan that ctags performs on the source file 
does not include that information.
It's a missing feature of ctags I suppose.

I remember that I wrote a patch against ctags to get the return type of 
a function, and that I implemented a way to get the pointer type of a 
variable in the cxx-parser, using some code from CodeLite - and a lexer.
You can look at parser-cxx plugin.

Anyway please note that currently symbol-db won't give you the pointer 
info because its ctags-backend doesn't provide it.

The best choice would be to replace totally ctags in view of a clang 
based parser.
