Adjust various man pages and other documentation to point to capfile(5)
instead of termcap(5).
Remove getcap(3) as curses hasn't been building it for a long time.
Punt wrterm.c as tset no longer uses it.
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.
-call setlocale(LC_CTYPE, "") before nl_langinfo(CODESET) if the
locale settings is (still) at "C" - otherwise the CODESET doesn't work
-fix the type of the WACS_* symbols -- this needs to be cchar_t*
-add safeguards where the return value of wcwidth() is used for
loop counters or indexing -- it can be -1
-use more common code in the widechar support case -- in particular
let the wchar functions do the work even if chtype ones were called
-implement wcursyncup/wsyncup/wsyncdown
-somewhat experimental: allow ACS_* variables to refer to WACS_*
table entries -- this way, programs using the old chtype using API
can use UTF8 line drawing on terminals which support UTF8 but not
ACS switching
-fix some logics bugs in UTF8 recognition and ALTCHARSET handling
term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.
This makes our getch() and related functions conform to SUSv2.
Also fixes PR lib/15920.
XXX: This causes an API incompatability, but comes less than 27 hours after
the libcurses major number was incremented, so should have minimal impact.
1. delete the incorrect duplicate macro from unctrl.h
2. move unctrl macros from curses.h to unctrl.h and make curses.h include
unctrl.h in curses.h instead of duplicating their definition.
3. constify unctrl arrays; make length unsigned.
See the Single UNIX Specification, Version 2 :
http://www.opengroup.org/onlinepubs/007908799/xcurses/can_change_color.html
Also, add the functions :
use_default_colors();
assume_default_colors(fore, back);
(from ncurses) that allow the terminal default colours or user-specified
default colours to be used.
