This is sometimes necessary when using + overlapping windows, since a change to one window affects + the other window, but the records of which lines have been + changed in the other window do not reflect the change. + The routine <STRONG>touchline</STRONG> only pretends that <EM>count</EM> lines have + been changed, beginning with line <EM>start</EM>. + + The <STRONG>untouchwin</STRONG> routine marks all lines in the window as + unchanged since the last call to <STRONG>wrefresh</STRONG>. + + The <STRONG>wtouchln</STRONG> routine makes <EM>n</EM> lines in the window, starting + at line <EM>y</EM>, look as if they have (<EM>changed</EM><STRONG>=1</STRONG>) or have not + (<EM>changed</EM><STRONG>=0</STRONG>) been changed since the last call to <STRONG>wrefresh</STRONG>. + + The <STRONG>is_linetouched</STRONG> and <STRONG>is_wintouched</STRONG> routines return <STRONG>TRUE</STRONG> + if the specified line/window was modified since the last + call to <STRONG>wrefresh</STRONG>; otherwise they return <STRONG>FALSE</STRONG>. In addi- + tion, <STRONG>is_linetouched</STRONG> returns <STRONG>ERR</STRONG> if <EM>line</EM> is not valid for + the given window. + + +</PRE> +<H2>RETURN VALUE</H2><PRE> + All routines return the integer <STRONG>ERR</STRONG> upon failure and an + integer value other than <STRONG>ERR</STRONG> upon successful completion, + unless otherwise noted in the preceding routine descrip- + tions. + + X/Open does not define any error conditions. In this im- + plementation + + <STRONG>is_linetouched</STRONG> + returns an error if the window pointer is + null, or if the line number is outside the + window. Note that ERR is distinct from TRUE + and FALSE, which are the normal return values + of this function. + + <STRONG>wtouchln</STRONG> + returns an error if the window pointer is + null, or if the line number is outside the + window. + + +</PRE> +<H2>PORTABILITY</H2><PRE> + The XSI Curses standard, Issue 4 describes these func- + tions. + + 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>.
