Xlib

Xlib is a software library that provides a programming interface to interact with the X Window System, which manages graphical displays on many Unix and Linux operating systems. It allows applications to create, control, and communicate with graphical elements like windows, buttons, and menus by sending commands to the display server. Essentially, Xlib acts as a bridge between software and the computer’s graphical environment, enabling developers to build and manage visual interfaces in a standardized way. It handles low-level details of rendering graphics, user input, and display management, facilitating the development of graphical applications on compatible systems.
