Middleware

This section covers the LibXR middleware for system services, communication, and terminal interaction.

The middleware consists of logging, events, messaging (in-process Topic, packet packing and parsing, Linux shared-memory Topic), a Flash key-value database, an in-memory file system, and a command-line terminal. Topic supports synchronous, asynchronous, queued, and callback subscribers; the database adapts to different Flash minimum write units.
