The KeRemoveDeviceQueue routine removes an entry from the head of a specified device queue.
DeviceQueue [in, out]Pointer to an initialized device queue object for which the caller provides the storage.
If the device queue is empty but is set to a busy state, KeRemoveDeviceQueue returns NULL.
The specified device queue spin lock is acquired and the state of the device queue is checked. If the device queue is set to a busy state and an IRP is queued, this routine dequeues the entry and returns a pointer to the IRP. A call to KeRemoveDeviceQueue when the device queue object is set to a busy state but no IRPs are queued causes a state change to not-busy. The specified device queue's spin lock is released.
It is an error to call KeRemoveDeviceQueue when the device queue object is set to a not-busy state.
