Value Description

A document lock is requested by calling ITextStoreAnchor::RequestLock. The application grants the lock request by calling ITextStoreAnchorSink::OnLockGranted with the requested lock type. The lock is only valid during the OnLockGranted call. When OnLockGranted returns, the document is considered unlocked.

The lock type, specified in dwLockFlags, must match the requested lock type in the corresponding call to ITextStoreAnchor::RequestLock.

Calls to ITextStoreAnchor::RequestLock from within OnLockGranted will return an error value.

Applications must not call any of the ITextStoreAnchorSink methods from within the context of OnLockGranted.

If a synchronous lock request is made from within ITextStoreAnchor::RequestLock, then the caller must also provide the return value from ITextStoreAnchor::RequestLock.
