Routine Description:
Dispatch routine for device control ioctls.
Arguments:
Irp - Pointer to I/O request packet
IrpSp - Pointer to the current stack location in the Irp.
Return Value:
NTSTATUS -- Indicates whether the request was successfully queued.
Notes:
Any IRP for which the return value is not STATUS_PENDING will be
completed by the calling routine.
