without refresh. If the window is not dirty but the window cursor
position does not match curscr then move the cursor. This fixes
the issues seen in PR lib/54263.
Keep track of the cursor location, if getch is called without a refresh
and without pending updates (dirty windows) then move the cursor to the
correct location directly. Doing this prevents unnecessary refreshes.
This makes it more portable as open_memstream is POSIX and fixes a
potential issue with wide characters not fully being printed
due to any buffer overflow.
doesn't work that well. addstr() the whole buffer instead. This is
still not enirely correct b/c printf can run out of stdio buffer
mid-character for very long output, but deal with it later.
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
(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.

HEAPS guys!
Standard curses library use eight bit for standout mode, so
8-bit characters displays like highlighted 7-bit characters.
This patch produce library which is fully compatible with all curses
programs and add 8-bit chars to all input/display functions.

I don't think, that any programs wish to use internal curses
attribute _STANDOUT directly, in expressions like:
addch( ch | _STANDOUT );
Normal interface use standout() and standend() functions instead.
Many programs use 'char' type (with sign extention) for input characters
and sign extention becomes _STANDOUT mode in this case.
So, I refuse this future and allow 8-bit characters for programs,
which is designed for 7-bit only ('char' type using instead of
'unsigned char').

This small patch fix unpleasant standard curses bug:
curses can't expand TAB at all (but tries).
A man who wrote this curses misplace SYNC_IN and SYNCH_OUT,
this patch exchange macro calls.
This patch useful for standard 7-bit curses too, for this
you must delete '_' symbol before waddbytes and apply patch.

Oh, NO! This curses are really buggy!
This small patch fix following problem:
[ assumed scrollok(stdscr, TRUE) ]
when addch(ch) at lower right corner of screen, curses are realy
gone mad instead if simple scrolling... Curses code assumed that
this will be done correctly, but implement it with two bugs.
