1.14 nicm 39: * Each window is attached to a number of panes, each of which is a pty. This
1.1 nicm 40: * file contains code to handle them.
41: *
42: * A pane has two buffers attached, these are filled and emptied by the main
43: * server poll loop. Output data is received from pty's in screen format,
44: * translated and returned as a series of escape sequences and strings via
45: * input_parse (in input.c). Input data is received as key codes and written
46: * directly via input_key.
47: *
48: * Each pane also has a "virtual" screen (screen.c) which contains the current
49: * state and is redisplayed when the window is reattached to a client.
50: *
51: * Windows are stored directly on a global array and wrapped in any number of
52: * winlink structs to be linked onto local session RB trees. A reference count
53: * is maintained and a window removed from the global list and destroyed when
54: * it reaches zero.
