- The XSI Curses standard is ambiguous on the question of
- whether <STRONG>raw</STRONG>() should disable the CRLF translations con-
- trolled by <STRONG>nl</STRONG>() and <STRONG>nonl</STRONG>(). BSD curses did turn off these
- translations; AT&T curses (at least as late as SVr1) did
- not. We choose to do so, on the theory that a programmer
- requesting raw input wants a clean (ideally 8-bit clean)
- connection that the operating system will not alter.
-
- Some historic curses implementations had, as an undocu-
- mented feature, the ability to do the equivalent of
- <STRONG>clearok(...,</STRONG> <STRONG>1)</STRONG> by saying <STRONG>touchwin(stdscr)</STRONG> or <STRONG>clear(std-</STRONG>
- <STRONG>scr)</STRONG>. This will not work under ncurses.
-
- Earlier System V curses implementations specified that
- with <STRONG>scrollok</STRONG> enabled, any window modification triggering
- a scroll also forced a physical refresh. XSI Curses does
- not require this, and <STRONG>ncurses</STRONG> avoids doing it to perform
- better vertical-motion optimization at <STRONG>wrefresh</STRONG> time.
-
- The XSI Curses standard does not mention that the cursor
- should be made invisible as a side-effect of <STRONG>leaveok</STRONG>.
- SVr4 curses documentation does this, but the code does
- not. Use <STRONG>curs_set</STRONG> to make the cursor invisible.
