X Window System Application Interface

Category: Desktop [UA]

This Product Standard provides X Window System user interface services to applications via a programmatic interface. It includes the Xlib interface, the X Protocol, ICCCM, and the Xt Intrinsics, at the X11 Release 4 level. It is optional whether the displays are local and/or remote and whether they employ the X Protocol (that is, the focus of this Product Standard is application portability).

Product Standards are explained in Practical Guide to the Open Brand
