Detailed Description

Mutex - provides synchronization, the ability to control how threads share resources. You use mutexes to prevent multiple threads from modifying shared data at the same time, and to ensure that a thread can read consistent values for a set of resources (for example, memory) that may be modified by other threads.

Locks the mutex. If the mutex is currently locked, the calling thread is blocked until mutex is unlocked. On return, the thread owns the mutex until it calls Mutex::unlock().

void System::Mutex::unlock
