SHORT-TERM TO-DO ITEMS:
+ Scrolling optimization has holes: for example, it forces repaints of the
screen between calls to refresh().
-+ SVr4 uses slightly different rules for determining when softkeys are shown.
++ SVr4 uses slightly different rules for determining when softkeys are shown.
For example, they are initially displayed (before the ncurses 'e' test
activates them), and a touchwin can apparently also force them to be
displayed.
+ The window classes defined in the c++ subdirectory need documentation. Some
C++ programmer could earn a lot of good karma by doing this...
-+ vid_attr() should support the set_a_attributes (sgr1) string, but does not.
++ vid_attr() should support the set_a_attributes (sgr1) string, but does not.
There appear to be no terminals that require that functionality.
++ the configure --disable-ext-funcs option does not work for Ada95 tree.
+
++ the --with-pthread configuration builds for Cygwin, but does not work
+ properly (test/worm.c shows all of the worms in the same location).
+
++ the --enable-rpath configure option builds for the corresponding platforms;
+ however combining it with --with-ticlib and --with-termlib does not always
+ produce libraries that can be run without setting environment variables.
+ Building those with libtool does not work either. (This is a problem with
+ the BSD platforms).
+
++ more work is needed to make the MinGW port support ordinary terminals.
+
Portability (or lack thereof):
+ Users of older System V UNIXes (but not Solaris, and probably not SVr4) may
trip over a known problem with the signal-handling code which causes abrupt
termination of ncurses applications following resume from a ^Z suspend (this
problem was first seen running lynx). You will not see this problem if you
- are running Linux or one of the 4.4BSD derivatives like FreeBSD, NetBSD, or
- BSDI. For details, see the analysis in the header comment of
- ncurses/tty/lib_tstp.c .
+ are using one of the 4.4BSD derivatives like such as, NetBSD, or BSDI, or
+ systems using that convention. For details, see the analysis in the header
+ comment of ncurses/tty/lib_tstp.c .
+ In theory, vwprintw and vwscanf are supposed to use the older varargs.h
interface for handling variadic argument lists (and are deprecated by X/Open
- for that reason). Linux doesn't have varargs.h, it has the newer
- X/Open-standard stdargs.h equivalent. So these functions use stdargs
- instead. This is unlikely to be a problem unless you're building ncurses on
- a System V old enough to only have varargs.h. (Solaris 2.5.1 used the
- stdarg.h binding as well).

-+ If you're using a BSD earlier than 4.4BSD, or a Linux old enough not to have
- a native vsscanf(3) in its library, vwscanw() will not work. You lose. (It
- should work on any System V, however). If you want to fix this, add an
