how do I tell the size of a pseudoterm window?

[David Lai]

2 problems:

1) How is a program able to tell the size of a pseudoterm's window.
   Is there a termcap entry which specifies that the screen can be
   resized? (The termcap man pages dont mention it).  How does a program
   get 'signalled' when a resize occurs (ie. like vi doing a redraw after
   a resize) ?

2) How can the termcap be modified automatically when a 'resize' occurs, when
   not in a program (ie at the shell prompt)?  This would be useful so that
   the next 'ls' or other such commands would output an appropriate number
   of columns.

I am looking for a general case solution which should be able to be
applied to various windowing systems.  Does this involve a special
tty/pty driver?
