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.
