Good C Books for Reference (Wich one(s) should I buy?)

I well I'm a CS student, so I saved some of my money in order to buy some programming books, as I haven't much money to spare then I would like to use it the best way. My University Library already has the following famous books (so I wont buy them):

C How to Program by Deitel and Deitel
The C Programming Language by Schildt
The ANSI C Programming Language by Kernighan and Richie
Programming in C/C++ The Bible by Kris Jamsa and Lars klander

I was looking for something good for Linux programming, and also some strong reference for deeper topics, so what would you suggest me to buy?
Thx a lot by the patience.

I'd suggest a forum search, you'll find this one has been asked before... :)

But only once. Every week.

if your looking for *nix programming, theres a pretty informative book called "Advanced Programming in the Unix Environment" or something like that. I didnt use it all that much (as with so many of my text books) but what i did read of it was pretty good.
