Detailed Description

Implements a very fast, non reentrant mutex.

This is the fastest and smallest possible mutex. To be used when implementing the condition/mutex raw scheme or when a very small section of uninterruptable code is to be protected.

All mutex classes are implemented via inline calls to maximize execution speed; also, their metods are extremely small.

Constructor & Destructor Documentation

Wefts::Mutex::Mutex (    )  [inline]

Initializes the internal data of the mutex.

Wefts::Mutex::~Mutex (    )  [inline]

Destroys the mutex. Only call this when the mutex is fully unlocked: destroyng a locked mutex has undefinded result.

Member Function Documentation

virtual void Wefts::Mutex::lock (    )  [inline, virtual]

Locks the mutex. If the calling thread is already owning the lock, the function will block producing an unavodiable and unininterruptable deadlock. Reimplemented in Wefts::RMutex.

virtual void Wefts::Mutex::unlock (    )  [inline, virtual]

Unlocks the mutex. This method does not checks if the calling thread is the rightful owner of the mutex; unlocking a mutex from a thread that has not locked it has an undefined outcome. Reimplemented in Wefts::RMutex.
