IAdapterPnpManagement::PnpQueryStop method (portcls.h)

  • Article

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.

For more information, see Implement PnP Rebalance for PortCls Audio Drivers.
