libwaylandserver

libwaylandserver is a C library that provides the server-side implementation of the Wayland protocol. Wayland is a protocol for a display server and its clients. The protocol itself is simple and extensible, and libwaylandserver implements the core functionality required for a Wayland compositor to function.

The library handles the low-level details of communication between the compositor and Wayland clients over an IPC mechanism, typically a Unix domain socket. It manages the parsing and dispatching of Wayland protocol requests and events. libwaylandserver is responsible for maintaining the state of Wayland objects, such as displays, surfaces, and buffers, as well as enforcing the protocol's rules.

Key features of libwaylandserver include its event loop integration, allowing compositors to seamlessly incorporate Wayland event handling into their existing event processing. It also provides mechanisms for managing object lifecycles and permissions. Compositors built using libwaylandserver can offer modern graphics features and a secure, efficient windowing system.

This library is a fundamental component for any Wayland compositor project, enabling the development of graphical environments that adhere to the Wayland protocol. It is often used in conjunction with other libraries like libinput for input handling and Mesa for graphics rendering.
