libxcb-sync-dev - 1.17.0-2+b1 main

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