libxcb-xlib0-dbg 1.1-1ubuntu1.1 (ia64 binary) in ubuntu hardy

 This package contains the debugging symbols associated with libxcb-xlib, the
 Xlib/XCB interface for the X C Binding. gdb will automatically use these
 symbols when debugging libxcb-xlib. 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
