2 | # | |
3 | # This library is no longer being maintained, and is included for backward | |
4 | # compatibility with Perl 4 programs which may require it. | |
5 | # | |
6 | # In particular, this should not be used as an example of modern Perl | |
7 | # programming techniques. | |
8 | # | |
9 | # Suggested alternative: Term::Cap | |
10 | # | |
11 | ;# | |
12 | ;# Usage: | |
13 | ;# require 'ioctl.pl'; | |
14 | ;# ioctl(TTY,$TIOCGETP,$foo); | |
15 | ;# ($ispeed,$ospeed) = unpack('cc',$foo); | |
16 | ;# require 'termcap.pl'; | |
17 | ;# &Tgetent('vt100'); # sets $TC{'cm'}, etc. | |
18 | ;# &Tputs(&Tgoto($TC{'cm'},$col,$row), 0, 'FILEHANDLE'); | |
19 | ;# &Tputs($TC{'dl'},$affcnt,'FILEHANDLE'); | |
