The KSDEVICE_DISPATCH structure describes the callbacks that a client can provide to receive notification of device creation and PnP events.
AddOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceAdd callback routine.
StartOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceStart callback routine.
PostStartOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDevicePostStart callback routine.
QueryStopOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceQueryStop callback routine.
CancelStopOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceCancelStop callback routine.
StopOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceStop callback routine.
QueryRemoveOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceQueryRemove callback routine.
CancelRemoveOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceCancelRemove callback routine.
RemoveOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceRemove callback routine.
QueryCapabilitiesOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceQueryCapabilities callback routine.
SurpriseRemovalOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceSurpriseRemoval callback routine.
QueryPowerOptional. can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceQueryPower callback routine.
SetPowerOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceSetPower callback routine.
QueryInterfaceOptional. Can be NULL. A pointer to a minidriver-supplied AVStrMiniDeviceQueryInterface callback routine.
In describing a device with the KSDEVICE_DESCRIPTOR structure, clients include a pointer to a dispatch table defined by this structure. Any member of this structure may be NULL indicating that the minidriver receives no notification for that particular message.
