Darwin-kernel mailing list (Darwin-kernel@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-kernel/site_archiver%40lists.a... i have an already working kext which writes to syslog without any problems. However what i actually want is an application (maybe daemon) which receives this messages from my kext. I was thinking about reading from the syslog but this doesn't look like a very efficient and elegant solution. My question is: How can a kext pass messages to a user space application? Is there at least any documentation and/or examples on this or does anyone have a suggestion on how to start here? I assume that this is not such a big issue? But it's the only (and of course most important) part that is missing missing? Check out USBProberV2 in the IOUSBFamily sources. It has everything you need to log messages from a kext in a userland process. This email sent to site_archiver@lists.apple.com
