== 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.
