class TMutex: public TVirtualMutex


This class implements mutex locks. A mutex is a mutual exclusive
lock. The actual work is done via the TMutexImp class (either
TPosixMutex or TWin32Mutex).

Function documentation

TMutex(Bool_t recursive)
 Create a mutex lock. The actual mutex implementation will be
 provided via the TThreadFactory.
Int_t Lock()
 Lock the mutex. Returns 0 when no error, EDEADLK when mutex was already
 locked by this thread and this mutex is not reentrant.
Int_t TryLock()
 Try to lock mutex. Returns 0 when no error, EDEADLK when mutex was
 already locked by this thread and this mutex is not reentrant.
Int_t UnLock()
 Unlock the mutex. Returns 0 when no error, EPERM when mutex was already
 unlocked by this thread.
Int_t CleanUp()
 Clean up of mutex if it belongs to thread.
TVirtualMutex * Factory(Bool_t recursive = kFALSE)
 Create mutex and return pointer to it. Calling function must care
 about proper deletion. The function is intended to be used in connection
 with the R__LOCKGUARD2 macro for local thread protection. Since "new" is
 used the TStorage class has to be protected by gGlobalMutex.
TMutex(const TMutex&)
TMutex& operator=(const TMutex& )
virtual ~TMutex()
{ delete fMutexImp; }
