Multithreading.md

 Pre-requisite for this tutorial is having a basic understanding of what threads are and the main methods to synchronize them.

 Miosix provides two different interfaces for creating and managing threads: the `pthread` API and a navite one. Here we will consider only the native one.

 * `argv`: a `void*` pointer that is passed as a parameter to the entry point function.
 * `options`: thread options, such ad `Thread::JOINABLE`. By default native threads are not joinable, which means they will never end. The `join()` method allows to wait for a thread to end its execution.

 In this example two threads make two LEDs blink. The first one changes state two times every second while the second one is set "high" only when the on-board user button is pressed (the discovery's blue button).

+## Threads Synchronization
 Miosix also provides primitives, in order to synchronize the execution of multiple threads, such as mutexes and condition variables.  
 
 A mutex can be created as a global variable. Note that `Mutex` is a C++ class, and thus it has a constructor, so it initializes itself. The Miosix API provides two mutex classes: `Mutex` and `FastMutex`. `Mutex` has support for priority inheritance, while `FastMutex` is optimized for fastest lock/unlock.
