According to TN 2083, it is possible starting with Mac OS X 10.5 to start a daemon with launchd using a Mach Port. (1) I looked for sample code in the documentation, Technote and Google with no results so far. I think you just use the launchd API just like it's done in SampleD (http://developer.apple.com/samplecode/SampleD/ ). But instead of retreiving sockets (using LAUNCH_JOBKEY_SOCKETS and launch_data_get_fd()) you retreive your mach port (using LAUNCH_JOBKEY_MACHSERVICES and launch_data_get_machport()). The way to define a service in your plist is defined in the MachServices section of launchd.plist reference (man launchd.plist). And in the client application, you retreive it using bootstrap_look_up() (from <servers/bootstrap.h>). You can use the launch(3) API, but it's far easier to just use bootstrap_check_in() to get your receive right. -- Damien Sorresso BSD Engineering Apple Inc. smime.p7s
