  2. *
  3. * dynamic window manager is designed like any other X client as well. It is
  4. * driven through handling X events. In contrast to other X clients, a window
  5. * manager selects for SubstructureRedirectMask on the root window, to receive
  6. * events about window (dis-)appearance. Only one X connection at a time is
  7. * allowed to select for this event mask.
  8. *
  9. * Calls to fetch an X event from the event queue are blocking. Due reading
  10. * status text from standard input, a select()-driven main loop has been
  11. * implemented which selects for reads on the X connection and STDIN_FILENO to
  12. * handle all data smoothly. The event handlers of dwm are organized in an
  13. * array which is accessed whenever a new event has been fetched. This allows
  14. * event dispatching in O(1) time.
  15. *
  16. * Each child of the root window is called a client, except windows which have
  17. * set the override_redirect flag. Clients are organized in a global
  18. * doubly-linked client list, the focus history is remembered through a global
  19. * stack list. Each client contains an array of Bools of the same size as the
  20. * global tags array to indicate the tags of a client.
  21. *
  22. * Keys and tagging rules are organized as arrays and defined in config.h.
  23. *
  24. * To understand everything else, start reading main().
