Send information from kernel to user space RRS feed

  • Question

  • Hi,

    I have created a WFP driver based on ddProxy sample. Can anyone please tell me an efficient way to initiate a communication from kernel space to user space.

    I have created a device using IoCreateDevice() function is there any way i can use this to send information to user-space application, (i.e) if i specify "DeviceExtensionSize" > 0 can i read this buffer from user-space?

    please help...

  • This topic is beyond the scope of this particular forum.  To get you started, you should look into implementing and handling IOCtls.  Windows Via C / C++ and Windows Internals are a good resource for this topic.  The following link will steer you in the right direction as well:


    Hope this helps
