DO_DEVICE_INITIALIZING 的目的是防止其它组件在驱动程序完成初始化设备对象之前向设备发送 I/O。 每次打开设备的一个句柄时,以及任何时候驱动程序试图附加到一个设备堆栈时(检查堆栈顶部设备对象的这个标志),I/O 管理器都检查 DO_DEVICE_INITIALIZING。如果设置 DO_DEVICE_INITIALIZING,那么 I/O 管理器将不允许另一...
使用_Kernel_clear_do_init_批注指定批注函数是否应清除设备对象的“标志”字段中的DO_DEVICE_INITIALIZING位。此批注具有以下语法:C++ 复制 _Kernel_clear_do_init_(yes|no) 调用批注为 yes _Kernel_clear_do_init_ (的函数) 可免除调用函数清除DO_DEVICE_INITIALIZING位。当...
DO_DEVICE_INITIALIZING 这个东西的位置在DEVICE_OBJECT的Flags字段中, 本来这个Flags大多的情况下都是在设置IO方式,如DO_BUFFERED_IO, 但特殊的位也可能需要在这里设置。 用处是防止当自己的设备对象初始化完成之前,别的模块来发送信息给自己的模块的。 如果程序仅在DriverEntry中创建DeviceObject的话,那么当前位将由I...
创建筛选器设备对象时, IoCreateDevice 在设备对象上设置DO_DEVICE_INITIALIZING标志。 成功附加筛选器后,必须清除此标志。 如果未清除此标志,则无法再将筛选器驱动程序附加到筛选器链,因为对 IoAttachDeviceToDeviceStackSafe 的 调用将失败。无需清除 在DriverEntry 中创建的设备对象上的DO_DEVICE_INITIALIZING标志,因为...
When a device driver creates a device object by calling IoCreateDevice, the I/O manager sets DO_DEVICE_INITIALIZING in the Flags field of the DEVICE_OBJECT structure. The purpose of DO_DEVICE_INITIALIZING is to prevent other components from sending I/O to a device before the driver has finish...
After initializing the password of the root administrator _super_admin, ensure that you will remember the password. If you forget the password, you cannot perform operations that require the corresponding permissions. For example, if the password of the root administrator _super_admin is lost, you...
