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...

IRP_MJ_INTERNAL_DEVICE_CONTROL requests are used only for communication among kernel-mode components. While an IRP_MJ_DEVICE_CONTROL request usually originates with a call toDeviceIoControlorZwDeviceIoControlFile, these routines can't create IRP_MJ_INTERNAL_DEVICE_CONTROL requests. However, both types...

The IRP_MJ_INTERNAL_DEVICE_CONTROL request sets internal operating modes on a mouse device. Lower-level drivers use internal device control requests to connect and operate a mouse device. Input Parameters Request-specific. Output Parameters
对于IRP_MJ_READ和IRP_MJ_WRITE,则不会用到这个缓冲区。对于 IRP_MJ_DEVICE_CONTROL 或 IRP_MJ_INTERNAL_DEVICE_CONTROL这两类IRP,该缓冲区被作为DeviceIoControl函数的输入缓冲区。该缓冲区 的长度由IO_STACK_LOCATION结构(后面会讲到该结构)中的 Parameters.DeviceIoControl.InputBufferLength 成员来确定。
