Constructor & Destructor Documentation

IlsRWLocker()

IlsRWLocker::IlsRWLocker	(	IlsRWLock *	m = 0,

Member Function Documentation

assign()

void IlsRWLocker::assign	(	IlsRWLock *	m = 0,
		IlsRWLockType	t = ILS_NO_LOCK
	)

This member function assigns the readers/writer lock.

The readers/writer lock can be assigned at any time. Setting the assigned readers/writer lock to zero will prevent the readers/writer lock from being unlocked when the readers/writer lock wrapper is destroyed. Assigning a readers/writer lock will cause the old readers/writer lock, if any, to be unlocked, and the new readers/writer lock, if any, to be locked.
