Other than the window, each argument is a character with attributes: <EM>ls</EM> - left side, <EM>rs</EM> - right side, <EM>ts</EM> - top side, <EM>bs</EM> - bottom side, <EM>tl</EM> - top left-hand corner, <EM>tr</EM> - top right-hand corner, <EM>bl</EM> - bottom left-hand corner, and <EM>br</EM> - bottom right-hand corner. If any of these arguments is zero, then the corresponding default values (defined in <STRONG>curses.h</STRONG>) are used instead: <STRONG>ACS_VLINE</STRONG>, <STRONG>ACS_VLINE</STRONG>, <STRONG>ACS_HLINE</STRONG>, <STRONG>ACS_HLINE</STRONG>, <STRONG>ACS_ULCORNER</STRONG>, <STRONG>ACS_URCORNER</STRONG>, <STRONG>ACS_LLCORNER</STRONG>, <STRONG>ACS_LRCORNER</STRONG>. <STRONG>box(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>)</STRONG> is a shorthand for the following call: <STRONG>wborder(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG> <STRONG>0)</STRONG>. The <STRONG>hline</STRONG> and <STRONG>whline</STRONG> functions draw a horizontal (left to right) line using <EM>ch</EM> starting at the current cursor posi- tion in the window. The current cursor position is not changed. The line is at most <EM>n</EM> characters long, or as many as fit into the window. The <STRONG>vline</STRONG> and <STRONG>wvline</STRONG> functions draw a vertical (top to bottom) line using <EM>ch</EM> starting at the current cursor posi- tion in the window. The current cursor position is not changed. The line is at most <EM>n</EM> characters long, or as many as fit into the window.</PRE><H2>RETURN VALUE</H2><PRE> All routines return the integer <STRONG>OK</STRONG>. The SVr4.0 manual says "or a non-negative integer if <STRONG>immedok</STRONG> is set", but this appears to be an error. X/Open does not define any error conditions. This imple- mentation returns an error if the window pointer is null.</PRE><H2>NOTES</H2><PRE> The borders generated by these functions are <EM>inside</EM> bor- ders (this is also true of SVr4 curses, though the fact is not documented). Note that <STRONG>border</STRONG> and <STRONG>box</STRONG> may be macros.</PRE><H2>PORTABILITY</H2><PRE> These functions are described in the XSI Curses standard, Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on failure, but specifies no error conditions.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_outopts.3x.html">curs_outopts(3x)</A></STRONG>. <STRONG><A HREF="curs_border.3x.html">curs_border(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
