X Window System Unified Protocol
This package provides the headers and specification documents defining the core protocol and (many) extensions for the X Window System. The extensions are those common among servers descended from X11R7. It also includes a number of headers that aren't purely protocol related, but are depended upon by many other X Window System packages to provide common definitions and porting layer.
Though the protocol specifications herein are authoritative, the content of the headers is bound by compatibility constraints with older versions of the X11 suite. If you are looking for a machine-readable protocol description suitable for code generation or use in new projects, please refer to the XCB project:
