These are Sun specific features to get and set the window size.
TIOCSSIZE is the ioctl to set the screen size (which a window manager
must do) and in termlib, the corresponding ioctl TIOCGSIZE is used
to find out the size for vi and curses.  ttysize is the structure
passed to these ioctls.

There is no corresponding feature in vanilla 4.2BSD, which lacks a
window manager and the concept of a window size.  It is not heard
to add such a feature to the pty driver, however.  It has been added
in the AT&T 5620 window manager, for example, using the JWINSIZE
and JSWINSIZE ioctls.  Presumably X has yet a third incompatible
set of ioctls.  Sure would be nice if P.1003 would standardize this.
Fortunately, only window managers and termlib/curses care, it's
transparent to ordinary applications.
