The I/O Manager, other operating system components, and other kernel-mode drivers send IRP_MJ_DEVICE_CONTROL requests. Normally this IRP is sent on behalf of a user-mode application that has called the Win32DeviceIoControlfunction or on behalf of a kernel-mode component that has calledZwDeviceI...

当另一个驱动程序调用IoBuildDeviceIoControlRequest或IoAllocateIrp来创建请求时,驱动程序会收到IRP_MJ_INTERNAL_DEVICE_CONTROL请求。 此I/O 控制代码已定义用于配对和分层内核模式驱动程序之间的通信,例如在端口驱动程序上分层的一个或多个类驱动程序。 更高级别的驱动程序使用特定于设备或驱动程序的 I/O 控制代码设置...

有关IRP_MJ_DEVICE_CONTROL或IRP_MJ_INTERNAL_DEVICE_CONTROL请求的 I/O 控制代码的常规信息,请参阅使用 I/O 控制代码。 另请参阅设备Type-Specific I/O 请求。 要求 标头 Wdm.h(包括 Wdm.h、Ntddk.h 或 Ntifs.h) 另请参阅 DispatchDeviceControl ...
Every driver whose device objects belong to a particular device type (see Specifying Device Types) is required to support this request in a DispatchDeviceControl routine, if a set of system-defined I/O control codes (IOCTLs) exists for the type.

这种通信方式，就是驱动程序和应用程序自定义一种IO控制码，然后调用DeviceIoControl函数，IO管理器会产生一个MajorFunction 为IRP_MJ_DEVICE_CONTROL（DeviceIoControl函数会产生此IRP），MinorFunction 为自己定义的控制码的IRP，系统就调用相应的处理IRP_MJ_DEVICE_CONTROL的派遣函数，你在派遣函数中判断MinorFunction ，是...
