Questing about the basic compilers

[Mejc]

Hi im a newb and recently used the following command to install the gcc and g++ compilers on my comp:
apt-get install build-essential. It all works great and no problems so far except that when i want to man some C funtions it says no entry for instance if i go man malloc or man strtok or man strsep i get no documentation. Is there anywhere i can get this documentation into man via command or some package

Thanks
