[comp.windows.x] Xtty, Xterm, and Multiple Windows

EASSON@BNR.BITNET (Ian Easson, I.) (10/02/87)

This relates to release 10.4.

I need to know how Xtty and Xterm combine to provide multiple VT100
windows.

XTerm provides a single VT102 emulation window. Xtty provides an
application interface to a number of these windows, as well as the
ability to create and kill a specified window. I assume that Xtty can
only kill a window that it created.

The documentation (Xtty.3X) states that Xtty manages these windows by
'creating a subprocess xterm(1) and communicating with it through a pty.'
It implies that only ONE Xterm process is created.

XTerm documentation however, never mentions multiple VT102 windows,
implying that it only manages one VT102 window.

The question then is this:

    Does Xtty really create only one xterm process which then
    manages all windows subsequently created by xtty, or does it
    in fact create  an xterm process per window that it creates?

Thanks for your efforts.
