I have been examining the kauthORama code on the apple web site. I am interested in monitoring file_open requests. Can anyone direct me to suitable documentation or examples whch explain the way or mechanisms to send messages or strings to user land applications? Would this involve the creation of ports? Can this done in a kext? Can you /should you send messages from a kext? Thanks, Trip _______________________________________________ Do not post admin requests to the list. They will be ignored.
