- .sp 2
- .)l
- .(q
- .pp
- 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.
- .)q
- .b Acknowledgements
- .pp
- 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.
