Hi there,
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.
