Using examples, guidelines and tutorials, as well as material on theory and practice, this reference provides information to knowledgable X users who want to learn about the basic interaction between client and server, including developers who want to port, extend, tune or test a server. Part 1, Architecture, discusses the structure of the sample server, including the server's major data structures and their interactions, the flow of control within the server, how the server handles input, devices and events, how the server maintains the window tree and how it keeps graphics context up to date with drawables. Part 2, Porting and Tuning, explains in detail the process of porting the server to new display hardware or a new operating syste, and discusses strategies for tuning an existing server. Part 3, Writing Extensions, describes the server extension mechanism, its interface and the design and implementation of new extensions.
