$Id: ReadKey.xs,v 2.22 2005/01/11 21:15:17 jonathan Exp $
Version 2.21, Sun Jul 28 12:57:56 BST 2002
Fix to improve the chances of automated testing succeeding
Version 2.20, Tue May 21 07:52:47 BST 2002
Patch from Autrijus Tang fixing Win32 Breakage with bleadperl
Version 2.19, Thu Mar 21 07:25:31 GMT 2002
Added check for definedness of $_[0] in comparisons in ReadKey, ReadLine
after reports of warnings.
Version 2.18, Sun Feb 10 13:06:57 GMT 2002
Altered prototyping style after reports of compile failures on
Windows.
Version 2.17, Fri Jan 25 06:58:47 GMT 2002
The '_' macro for non-ANSI compatibility was removed in 5.7.2
Version 2.16, Thu Nov 29 21:19:03 GMT 2001
It appears that the genchars.pl bit of the patch didnt apply
Applied the new ppport.h from Devel::PPPort
Version 2.15, Sun Nov 4 15:02:37 GMT 2001 (jns)
Applied the patch in
http:https://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2001-01/msg01588.html
for PerlIO compatibility.
Version 2.14, Sun Mar 28 23:26:13 EST 1999
ppport.h 1.007 fixed for 5.005_55.
Version 2.13, Wed Mar 24 20:46:06 EST 1999
Adapted to ppport.h 1.006.
Version 2.12, Wed Jan 7 10:33:11 EST 1998
Slightly modified test and error reporting for Win32.
Version 2.11, Sun Dec 14 00:39:12 EST 1997
First attempt at Win32 support.
Version 2.10, skipped
Version 2.09, Tue Oct 7 13:07:43 EDT 1997
Grr. Added explicit detection of sys/poll.h and poll.h.
Version 2.08, Mon Oct 6 16:07:44 EDT 1997
Changed poll.h to sys/poll.h.
Version 2.07, Sun Jan 26 19:11:56 EST 1997
Added $VERSION to .pm.
Version 2.06, Tue Nov 26 01:47:09 EST 1996
Added PERLIO support and removed duplicate declaration in .pm.
Version 2.05, Tue Mar 12 19:08:33 EST 1996
Changed poll support so it works. Cleaned up .pm a little.
Version 2.04, Tue Oct 10 05:35:48 EDT 1995
Whoops. Changed GetTermSize back so that GSIZE code won't be
compiled if GWINSZ is being used. Also took ts_xxx and ts_yyy
out of GSIZE.
Version 2.03, Thu Sep 21 21:53:16 EDT 1995
Fixed up debugging info in Readkey.pm, and changed TermSizeVIO
to use _scrsize(). Hopefully this is GO for both Solaris and OS/2.
Version 2.02, Mon Sep 18 22:17:57 EDT 1995
Workaround for Solaris bug wasn't sufficient. Modularlized
GetTermSize into perl code, and added support for the
`resize` executable. Hard coded path for Solaris machines.
Version 2.01, Wed Sep 13 22:22:23 EDT 1995
Change error reporting around in getscreensize so that if
an ioctl fails but getenv succeeds, no warning will be
printed. This is an attempt to work around a Solaris bug where
TIOCGWINSZ fails in telnet sessions.
Version 2.00, Mon Sep 4 06:37:24 EDT 1995
Added timeouts to select/poll, added USE_STDIO_PTR support
(required for recent perl revisions), and fixed up compilation
under OS/2.
Version 1.99, Fri Aug 11 20:18:11 EDT 1995
Add file handles to ReadMode.
Version 1.97, Mon Apr 10 21:41:52 EDT 1995
Changed mode 5 to disable UC & delays. Added more ECHO flags.
Tested termio[s] & sgtty.
Added termoptions so test.pl can give more info.
Version 1.96,
Mucked with filehandle selection in ReadKey.pm.
Version 1.95,
Cleaning up for distribution.
Version 1.94,
Dealt with get/settermsize sillyness.
Version 1.91, Sat Mar 11 23:47:04 EST 1995:
Andy's patches, and a bit of termsize finesse.
Version 1.9, Thu Mar 9 14:11:49 EST 1995:
Modifying for portability. Prototypes, singed chars, etc.
Version 1.8, Mon Jan 9 23:18:14 EST 1995:
Added use of Configure.pm. No changes to ReadKey.
Version 1.7, Fri Dec 16 13:48:14 EST 1994:
Getting closer to release. Added new readmode 2. Had to bump up other
modes, unfortunately. This is the _last_ time I do that. If I have to
bump up the modes again, I'm switching to a different scheme.
Version 1.6, Wed Dec 14 17:36:59 EST 1994:
Completly reorganized the control-char support (twice!) so that
it is automatically ported by the preproccessor for termio[s], or
by an included script for sgtty. Logical defaults for sgtty are included
too. Added Sun TermSize support. (Hope I got it right.)
Version 1.5, Fri Dec 9 16:07:49 EST 1994:
Added SetTermSize, GetSpeeds, Get/SetControlChars, PerlIO support.
Version 1.01, Thu Oct 20 23:32:39 EDT 1994:
Added Select_fd_set_t casts to select() call.
Version 1.0: First "real" release. Everything seems cool.
*******************************************************************/
/***
Things to do:
Make sure the GetSpeed function is doing it's best to separate ispeed
from ospeed.
Separate the stty stuff from ReadMode, so that stty -a can be easily
used, among other things.
