NSDistributedNotificationCenter is a way to send a notification out across the system. Only processes that are listening for the notification will receive it and have a chance to do something with it. It’s like yelling out in a crowded room to tell a single person something. Everyone will hear your message, but only one will be listening. Make sense? https://developer.apple.com/documentation/foundation/nsdistributednotificationcenter?changes=_4&language=objc
But what it really sounds like you want to use XPC (Cross Process Communication) for a more targeted messaging (possibly with payloads) between your app and menuling. https://developer.apple.com/documentation/xpc?language=objc —Rob > On Jul 25, 2023, at 7:51 AM, Gabriel Zachmann <z...@cs.uni-bremen.de> wrote: > > Thanks a lot for your responses! > > Sorry for the misunderstanding: I don't want to kill the other process. > (In case you forgot: the kill(2) system call is for sending unix signals to > processes, which can listen to those signals (at least, most of them).
