Subject: Using IPCSysV in a device driver

I am wondering if it is permitted to use message queues between a user
application and a device driver module...
Can anyone help me?

Thank you

It may be theoretically possible, but an easier and much more common
approach to this type of thing is for the driver to export an mmap()
interface. You could synchronize using poll() I think...
