Constructor & Destructor Documentation

◆ TMutex() [1/2]

TMutex::TMutex ( const TMutex )
private

◆ TMutex() [2/2]

TMutex::TMutex ( Bool_t  recursive = kFALSE)

Create a mutex lock.

The actual mutex implementation will be provided via the TThreadFactory.

Definition at line 34 of file TMutex.cxx.

◆ ~TMutex()

virtual TMutex::~TMutex ( )
inlinevirtual

Definition at line 43 of file TMutex.h.

Member Function Documentation

◆ CleanUp()

Int_t TMutex::CleanUp ( )
virtual

Clean up of mutex.

Implements TVirtualMutex.

Definition at line 76 of file TMutex.cxx.

◆ Factory()

TVirtualMutex * TMutex::Factory ( Bool_t  recursive = kFALSE)
virtual

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.

Implements TVirtualMutex.

Definition at line 87 of file TMutex.cxx.

◆ Lock()

Int_t TMutex::Lock ( )
virtual

Lock the mutex.

Returns 0 when no error, EDEADLK when mutex was already locked by this thread and this mutex is not reentrant.

Implements TVirtualMutex.

Definition at line 46 of file TMutex.cxx.

◆ operator=()

TMutex& TMutex::operator= ( const TMutex )
private

◆ TryLock()

Int_t TMutex::TryLock ( )
virtual

Try to lock mutex.

Returns 0 when no error, EDEADLK when mutex was already locked by this thread and this mutex is not reentrant.

Implements TVirtualMutex.

Definition at line 57 of file TMutex.cxx.

◆ UnLock()

Int_t TMutex::UnLock ( )
virtual

Unlock the mutex.

Returns 0 when no error, EPERM when mutex was already unlocked by this thread.

Implements TVirtualMutex.

Definition at line 68 of file TMutex.cxx.
