# Thread Synchronization Primitives

'''Include File(s):'''  [http://hg.libsdl.org/SDL/file/default/include/SDL_mutex.h SDL_mutex.h], [http://hg.libsdl.org/SDL/file/default/include/SDL_thread.h SDL_thread.h]


## Introduction

Functions in this group provide thread synchronization primitives for multi-threaded programing.

There are three primitives available in SDL:
* Mutex
* Semaphore
* Condition Variable

The SDL mutex is implemented as a recursive mutex so you can nest lock and unlock calls to the same mutex.
