cscope like functionality for C++ (using vim)

Is there any utility or plugin which provides cscope like functionality for C++. I am looking for

• all references to a symbol
• global definitions
• functions called by a function
• functions calling a function
• files including a file

Vim can interface directly with cscope out of the box. Type :h cscope. This requires cscope functionality to be enabled when Vim is compiled and for cscope to be installed on your computer.

There is a Vim + cscope tutorial on the cscope web page.
