About libxcb

libxcb provides an interface to the X Window System protocol, which replaces the traditional Xlib interface. It has several advantages over Xlib, including:

• size: small, simple library, and lower memory footprint
• latency hiding: batch several requests and wait for the replies later
• direct protocol access: interface and protocol correspond exactly
• proven thread support: transparently access XCB from multiple threads
• easy extension implementation: interfaces auto-generated from XML-XCB

Xlib also uses XCB as a transport layer, allowing software to make requests and receive responses with both, which eases porting to XCB. However, client programs, libraries, and toolkits will gain the most benefit from a native XCB port.
