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?

<http://developer.apple.com/documentation/DeviceDrivers/Conceptual/ WritingDeviceDriver/MakingHWAccessible/chapter_5_section_3.html#// apple_ref/doc/uid/TP30000698-TPXREF108> In this section there is a discussion of passing notifications from the kernel into user space. User space communication is initiated from user space to the kernel. Also, this might help <http://developer.apple.com/technotes/tn2005/ tn2083.html>. There is a lot of information in this document so you'll have to work at finding a solution for you. ...Duane _______________________________________________ Do not post admin requests to the list.
