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.

Member Function Documentation

void System::OldMutex::lock

(

)

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().

bool System::OldMutex::tryLock

(

)

void System::OldMutex::unlock

(

)

The mutex becomes unowned. If any threads are waiting for the mutex, one is awakened.
