Xynth Windowing System
What is? Xynth is a portable embedded windowing system, client/server interface between display hardware (mouse, keyboard, video displays) and the desktop environment that works on many hardware, including embedded devices (handhelds, set-top boxes, etc.).
  • TCP/IP (allows client/server connection on different hosts)
  • UDS (Unix Domain Sockets)
  • pipe() based socket api implementation. usefull for embedded devices. (there is no dependency for TCP/IP stack, if clients and server linked in singled app.)
  • Memory based pipe(), read(), send(), poll() implementation. xynth is able to work even there is no file descriptor on system.
  • mutex and condition variables implementation using semaphores.
  • DMA (Direct Memory Access). allows clients to draw directly on graphics buffer.
  • Buffer streaming (allows client/server connection on different hosts)
  • Move, 8-way resize
  • Optional theme plugin support. (theme_*.so)
    .xpm to .so tool.
  • Anti-aliased fonts with Freetype Library.
  • Anti-alias enabled low-level graphics library.
    (rgbcolor, colorrgb, setpixel, getpixel, hline , vline, fillbox, putbox, putboxmask, getbox, putboxpart, putboxpartmask, copybox, scalebox, getsurface, setsurfacevirtual, setsurface)
  • Anti-alias enabled overlay drawing ability.
    (rgbcolor_o, colorrgb_o, setpixel_o, getpixel_o, hline_o, vline_o, fillbox_o, putbox_o, putboxmask_o, getbox_o, putboxpart_o, putboxpartmask_o, copybox_o, getsurface_o, setsurfacevirtual_o, setsurface_o)
  • Basic image library.
    (xpm, png, gif)
  • Basic widget library.
    (object, frame, button, checkbox, textbox, scrollbuffer, listbox, controllistbox, pushbutton, etc.)
  • Low Memory & CPU Usage;
    In 1024x768x32bits mode with 253 clients open mem. usage is ~2,5M
  • Static linked binary : ~125K

POLL : Input polling.

Downloadable files, and svn repository (svn co xynth) are hosted at Logo.

You can safely use xynth svn, rather than waiting for tar ball releases. I always keep svn repository stable enough for every one. You can download the latest svn tar ball from sourceforge svn view, or directly from
