any resource for Linux C++

I need to learn how to deal with threads, daemons and redirection in C++. I'll surely have to learn more about *nix particularly Linux and C++. I'm expecially looking for simple code samples and libraries. A framework of a multi threaded C++ daemon will be a perfect starting. With the exception of http://www.boost.org/ I didn't find anything interesting. Also any pointer to C++ and Linux mailing lists will be welcome. THX
