Julian Orth 2b0c96c5ea xcb_in: Allow file descriptors to arrive early
The xserver sends file descriptors independently of replies. If the
server sends many events to the client, it is possible for the reply to
arrive several messages after the file descriptor.

The code already supported this but only if the intermediate messages
ended in partial packets.

With this patch, file descriptors will be buffered indefinitely until
they are consumed by a reply. There is still a limit of 16 file
descriptors imposed by the XCB_MAX_PASS_FD constant. If this limit is
exceeded, we call _xcb_conn_shutdown.

About libxcb

libxcb provides an interface to the X Window System protocol, which replaces the traditional Xlib interface. It has several advantages over Xlib, including:

  • size: small, simple library, and lower memory footprint
  • latency hiding: batch several requests and wait for the replies later
  • direct protocol access: interface and protocol correspond exactly
  • proven thread support: transparently access XCB from multiple threads
  • easy extension implementation: interfaces auto-generated from XML-XCB

Xlib also uses XCB as a transport layer, allowing software to make requests and receive responses with both, which eases porting to XCB. However, client programs, libraries, and toolkits will gain the most benefit from a native XCB port.

More information about xcb is available from our website:

Please report any issues you find to the freedesktop.org bug tracker at:

Discussion about XCB occurs on the XCB mailing list:
