- Some historic curses implementations had, as an undocumented feature,
- the ability to do the equivalent of <STRONG>clearok(...,</STRONG> <STRONG>1)</STRONG> by saying <STRONG>touch-</STRONG>
- <STRONG>win(stdscr)</STRONG> or <STRONG>clear(stdscr)</STRONG>. This will not work under ncurses.
+ The SVr4.0 manual says that these functions could return "a non-nega-
+ tive integer if <B>immedok</B> is set", referring to the return-value of <B>wre-</B>
+ <B>fresh</B>. In that implementation, <B>wrefresh</B> would return a count of the
+ number of characters written to the terminal.
