IAdapterPnpManagement::PnpQueryStop method (portcls.h)
PnpQueryStop provides a notification when PnpQueryStop is invoked by portcls just before succeeding the QueryStop IRP.
Syntax
void PnpQueryStop();
Return value
None
Remarks
PnpQueryStop is invoked by portcls just before succeeding the QueryStop IRP. This is just a notification and the call doesn’t return a value.
Note Portcls acquires the device global lock before making this call, thus the miniport must execute this call as fast as possible. While a Stop is pending, Portcls will block (hold) any new create requests.
