Specifically, if you link against the entire kernel you should have access to task_set_special_port, which is a necessary first step. You will also need to use MIG (in kernel mode!) to generate a demux routine. Make sure you don't export your catch_xxx routines, lest they collide with the kernel routines of the same name. For an example of this check out the "Mach exceptions to BSD signals" code inside the kernel itself. This email sent to site_archiver@lists.apple.com
