This document describes a package of C library functions
|
|
which allow the user to:
|
|
.ie t .ip \ \ \ \(bu
|
|
.el .ip 1)
|
|
update a screen with reasonable optimization,
|
|
.ie t .ip \ \ \ \(bu
|
|
.el .ip 2)
|
|
get input from the terminal
|
|
in a screen-oriented fashion,
|
|
and
|
|
.ie t .ip \ \ \ \(bu
|
|
.el .ip 3)
|
|
independent from the above, move the cursor optimally
|
|
from one point to another.
|
|
.pp
|
|
These routines all use the
|
|
\*(tc \*(db to describe the capabilities of the terminal.
|

|
|
This package would not exist
|
|
without the work of Bill Joy,
|
|
who,
|
|
in writing his editor,
|
|
created the capability to generally describe terminals,
|
|
wrote the routines which read this \*(db,
|
|
and, most importantly,
|
|
those which implement optimal cursor movement,
|
|
which routines I have simply lifted nearly intact.
|
|
Doug Merritt and Kurt Shoens also were extremely important,
|
|
as were both willing to waste time listening to me rant and rave.
|
|
The help and/or support of
|
|
Ken Abrams,
|
|
Alan Char,
|
|
Mark Horton,
|
|
and
|
|
Joe Kalash,
|
|
was, and is,
|
|
also greatly appreciated.

The help and/or support of Kirk McKusick and Keith Bostic (public vi!)
|
|
was invaluable in bringing the package ``into the 90's'', which now
|
|
includes completely new data structures and screen refresh optimization
|
|
routines.
