windows驱动程序基本结构:(1)初始化驱动程序，定位和申请硬件资源，创建内核对象(2)添加新设备(3)对PNP IRP进行缺省处理(4)对IRP_MN_REMOVE_DEVICE IRP进行处理(5)对即插即用IRP进行处理-windows driver for the basic structure of: (1) to initialize the driver, positioning and application of hardware resources, create a kernel object (2) add a new device (3) to the default PNP IRP handling (4) to deal with IRP_MN_REMOVE_DEVICE IRP ( 5) Plug and Play IRP processing
