Attributes (rendition) are stored with the characters. The <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG> <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.</PRE><H2>NOTES</H2><PRE> Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros. Reading a line that overflows the array pointed to by <EM>wch-</EM> <EM>str</EM> with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG> <STRONG>str</STRONG> causes undefined results. Therefore, the use of <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is recommended.</PRE><H2>RETURN VALUES</H2><PRE> Upon successful completion, these functions return <STRONG>OK</STRONG>. Otherwise, they return <STRONG>ERR</STRONG>.</PRE><H2>PORTABILITY</H2><PRE> The XSI Curses defines no error conditions. This imple- mentation checks for null pointers, returning ERR in that case.</PRE><H2>SEE ALSO</H2><PRE> Functions: <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_in_wch.3x.html">curs_in_wch(3x)</A></STRONG>, <STRONG><A HREF="curs_instr.3x.html">curs_instr(3x)</A></STRONG>, <STRONG><A HREF="curs_inwstr.3x.html">curs_inwstr(3x)</A></STRONG> <STRONG><A HREF="curs_in_wchstr.3x.html">curs_in_wchstr(3x)</A></STRONG></PRE><HR><ADDRESS>Man(1) output converted with<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a></ADDRESS></BODY></HTML>⌨️ 快捷键说明
