D-Bus is the established IPC on desktop Linux. The libdbus library is pretty old and not great, you'll have better luck using one of the other implementations.

D-Bus is the established IPC on desktop Linux. The libdbus library is pretty old and not great, you'll have better luck using one of the other implementations. I can recommend a few: - GDBus, if you're developing for GNOME - QtDBus, if you're developing for KDE - sd_bus, if you're writing low-level C - zbus, if you're using Rust For other languages, you'll want to look for bindings to one of those libraries, instead of bindings to libdbus.
