1.14 nicm 34: * Each window is attached to a number of panes, each of which is a pty. This
1.1 nicm 35: * file contains code to handle them.
36: *
37: * A pane has two buffers attached, these are filled and emptied by the main
38: * server poll loop. Output data is received from pty's in screen format,
39: * translated and returned as a series of escape sequences and strings via
40: * input_parse (in input.c). Input data is received as key codes and written
41: * directly via input_key.
42: *
43: * Each pane also has a "virtual" screen (screen.c) which contains the current
44: * state and is redisplayed when the window is reattached to a client.
45: *
46: * Windows are stored directly on a global array and wrapped in any number of
47: * winlink structs to be linked onto local session RB trees. A reference count
48: * is maintained and a window removed from the global list and destroyed when
49: * it reaches zero.
