Sorry for being so generic.
To be more specific, I have a kernel driver that is collecting information. I also have a user-space app that wants to get that information. I know that a basic way for the user-space app to get the information is to use an IOCTL call, but I was wonder if there wasn't a more efficient way do this. For one thing, with the IOCTL, I have to poll every x secs to determine if there is any information to read, which is very inefficient.
Hope that helps
