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 bool Wefts::Mutex::trylock   [inline, virtual]

Try to lock the mutex.

If any thread is currently holding the mutex, the function returns immediately false, while if it is not locked, the mutex is locked and the function returns true.

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.
