C in a Nutshell by Peter Prinz

The new edition of this classic O'Reilly reference provides clear, detailed explanations of every feature in the C language and runtime library, including multithreading, type-generic macros, and library functions that are new in the 2011 C standard (C11). If you want to understand the effects of an unfamiliar function, and how the standard library requires it to behave, you'll find it here, along with a typical example.
Ideal for experienced C and C++ programmers, this book also includes popular tools in the GNU software collection. You'll learn how to build C programs with GNU Make, compile executable programs from C source code, and test and debug your programs with the GNU debugger.
In three sections, this authoritative book covers:

C language concepts and language elements, with separate chapters on types, statements, pointers, memory management, I/O, and more

The C standard library, including an overview of standard headers and a detailed function reference

Basic C programming tools in the GNU software collection, with instructions on how use them with the Eclipse IDE
