Tags: x11 xcb protocol xorg bindings

About:
xcb-proto provides the XML protocol descriptions used by the libxcb code generator to create client-side bindings for the X Window System. It defines the requests, events, and errors of the X11 protocol in a machine-readable format. This package is essential for developers building applications that communicate with X11 servers.

Key Features:

XML-based protocol definitions for X11
Enables automated code generation for libxcb
Provides a language-agnostic specification of X11 protocol
Decouples protocol description from client library implementation

Use Cases:

Developing X11 client applications using libxcb
Generating custom language bindings for the X11 protocol
Cross-compiling X11-based software for different architectures

Alternatives:

xorg-server – Provides the X11 server implementation, whereas xcb-proto provides protocol definitions for client libraries.
libxcb – The generated client library that consumes xcb-proto definitions; xcb-proto is the input for its code generation.
