1 Overview

C11 is the informal name for ISO/IEC 9899:2011, the current standard for the C language that was ratified by ISO in December 2011.

It standardizes many features for safer programming, such as removal of gets() function.

Additionally, C11 adds concurrency support, type-generic expressions, alignment-related facilities, static assertion, unicode support, floating-point characteristic macros, no-return functions, anonymous structures and unions, and various bound-checking and reentrancy functions.

The following examples demonstrating C11 features can be compiled with options such as

clang -std=c11 ex.c

2 Multiple threading

C11 standardized multi-threading support.

It introduces new headers threads.h and stdatomic.h, supporting multiple threads of execution:

• threads creation and management
• mutexes
• conditional variables
• atomic objects
• thread specific storage
