Eclipse iceoryx™ - true zero-copy inter-process-communication

Project mention: Show HN: Comprehensive inter-process communication (IPC) toolkit in modern C++ | news.ycombinator.com | 2024-04-13

Also, when you want to perform some access control with access rights, you have to face sid— and ace-strings - oh they are fun. And, of course, there are all the nasty details; for instance, Windows defines macros that lead to compilation failures since they collide with internal naming. Take a look at this here, maybe it makes your efforts less painless: https://github.com/eclipse-iceoryx/iceoryx/blob/master/iceor...
You could reuse the iceoryx platform layer that enables iceoryx to run on every platform from qnx, linux, freertos, mac, windows. Maybe it can help you as well: https://github.com/eclipse-iceoryx/iceoryx/blob/master/doc/w...

[Start here!] Flow-IPC - Modern C++ toolkit for high-speed inter-process communication (IPC)

Oooh, so close. We’ve got the advertisement/discovery and messaging for sure.
Concretely what it would take to port it to those OS: https://github.com/Flow-IPC/ipc/issues/101
Given a couple weeks to work on it, this thing would be on macOS no problem. With Windows I personally need to understand its FD-passing and native handle concepts first, but I’m guessing it’d be a similar amount of effort in the end.
