This package contains the header and library files needed to build software using libxcb-randr, the randr 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
