X C Binding, dri2 extension
This package contains the library files needed to run software using libxcb-dri2, the dri2 extension for the X C Binding.
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
