KeInitializeDeviceQueue function (wdm.h)
The KeInitializeDeviceQueue routine initializes a device queue object to a not-busy state.
Syntax
void KeInitializeDeviceQueue(
[out] PKDEVICE_QUEUE DeviceQueue
);
Parameters
[out] DeviceQueue
Pointer to a device queue object for which the caller provides the storage.
Return value
None
Remarks
KeInitializeDeviceQueue initializes the specified device queue and sets its state to not-busy.
A driver should call KeInitializeDeviceQueue from its AddDevice routine after creating the device object for the associated device. Storage for the device queue object must be resident: in the device extension of a driver-created device object, in the controller extension of a driver-created controller object, or in nonpaged pool allocated by the caller.
