curses one is installed by:
1. not reinstalling the curses one after restarting
2. not sending KEY_RESIZE
Also, update the size of curscr, stdscr and __virtscr to match the new
screen size, so that their sizes are always updated.
Fixes the cases where applications call endwin() and then refresh() in
their SIGWINCH handler (i.e. the resizing problems in PR pkg/27777).
This fixes a problem where vi would not suspend.
Also, make sure that the signal handlers aren't set or removed multiple times.
Finally, add debug output when the signal handlers are set and removed.
Make set_prog_mode() set the correct settings.
I'm not certain how much restoration set_prog_mode() should do, but it
definitely doesn't want to do all of __restartwin().
Maybe __restartwin() should be calling set_prog_mode()?
Ensures we don't save the modified tty flags (as well as doing all the
initialisation twice) if the application (eg systat) calls curses functions
in its own restart code.
Allows error messages from programs like sysinst() to be seen.
(There is an explicit stopwin() before the error message is output,
and a second in the atexit() called cleanup() routine)
* Added code to __restartwin to restore meta and cursor visibility states
* Added code to __stopwin to disable meta.
* Added the *line group of functions for drawing character lines.
(this is a requirement of SUSv2) - the old macro behaviour can be
restored by defining _CURSES_USE_MACROS.
Changed function prototypes to use ANSI style.
All externally visible functions now have ANSI style declarations.
of the SYSV curses facilities. The added features are the collapsing
of arrow and function keysequences (as defined by termcap for the
terminal) into symbolic code returns thus relieving the application of
recognising multi-character key sequences. Other features are the
capability to perform a timed wait for a key (good for when you are
not sure if there is a keypress ready or not) and the capability for
turning off the inter-key timeout when assembling multi-character
function keys.
this work was done by Julian Coleman <J.D.Coleman@newcastle.ac.uk>
and blymn@baea.com.au (Brett Lymn). i'm just integrating it. thanks
HEAPS guys!
