DBus is a native D-Bus Inter-Process Communication (IPC) library for the U++ framework. This repository contains the core DBus components required to build both clients and servers entirely using native U++ code.

Features

   - Native Protocol Implementation: Speaks the D-Bus binary protocol directly using standard U++ Socket and String classes, avoiding external dependencies like libdbus or glib.
   - Event Loop Integration: Integrates easily with U++'s SocketWaitEvent for asynchronous messaging. It sleeps when idle and wakes on network traffic, ensuring it won't burn CPU cycles or freeze your GUI.
   - Full Client & Server Support: Query properties, call remote methods, claim well-known bus names, listen for incoming requests, and send structured replies seamlessly.
   - Built-in Authentication: Automatically handles standard D-Bus EXTERNAL handshakes to connect cleanly to both local session buses and system buses.

Examples
The DBus nest ships with ready-to-run interactive examples demonstrating both client-side and server-side setups, from basic blocking calls to background daemons.

   - Method        A basic example demonstrating D-Bus method calls.
   - Notify        A minimal client application demonstrating how to trigger a native desktop notification using a simple blocking method call.
   - Monitor       An asynchronous listener that subscribes to system-wide D-Bus broadcast signals and logs them to the console in real-time.
   - Marshall      Demonstrates how to marshall complex, poymorphic D-Bus data easily.
   - Properties    Demonstrates how to query and parse complex nested structures using the standard org.freedesktop.DBus.Properties interface.
   - Server        A headless background daemon that claims a well-known bus name and routes remote method requests asynchronously.
