How to view attached document of some API that is not in standard lib when using CDT in eclipse?
===

I'm using CDT (eclipse) when making some `ncurses` based applications.The problem is that I cannot view the attached document when using the lib. When I hover on some functions in **standard** library(such as `printf` and `getopt`),there is always a popup window containing the corresponding document.But it fails with the `ncurses` lib.

The os is Ubuntu 12.04 and I have installed the `ncurses-doc` package,which is *"developer's guide and documentation for ncurses"*.
