38 * Each window is attached to a number of panes, each of which is a pty. This
39 * file contains code to handle them.
41 * A pane has two buffers attached, these are filled and emptied by the main
42 * server poll loop. Output data is received from pty's in screen format,
43 * translated and returned as a series of escape sequences and strings via
44 * input_parse (in input.c). Input data is received as key codes and written
45 * directly via input_key.
47 * Each pane also has a "virtual" screen (screen.c) which contains the current
48 * state and is redisplayed when the window is reattached to a client.
50 * Windows are stored directly on a global array and wrapped in any number of
51 * winlink structs to be linked onto local session RB trees. A reference count
52 * is maintained and a window removed from the global list and destroyed when
