If the callback is currently being invoked, this function will not return until it completes. Thus, when calling this function, you must not hold any locks that the callback may also try to acquire lest you deadlock.
It is not necessary to unsubscribe before closing a session; all subscriptions are automatically canceled when the subscribing session terminates.
This function cannot be called from within a transaction. It will fail with FWP_E_TXN_IN_PROGRESS. See Object Management for more information about transactions.
FwpmvSwitchEventUnsubscribe0 is a specific implementation of FwpmvSwitchEventUnsubscribe. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.
