X C Binding, Xlib/XCB interface library, development files This package contains the header and library files needed to build software using libxcb-xlib, the Xlib/XCB interface for the X C Binding. libxcb-xlib contains portions of XCB used only by the Xlib/XCB compatibility layer; nothing other than Xlib should ever link to it. The XCB library provides an interface to the X Window System protocol, designed to replace the Xlib interface. XCB provides several advantages over Xlib: * Size: small library and lower memory footprint * Latency hiding: batch several requests and wait for the replies later * Direct protocol access: one-to-one mapping between interface and protocol * Thread support: access XCB from multiple threads, with no explicit locking * Easy creation of new extensions: automatically generates interface from machine-parsable protocol descriptions
