33 <H2>DESCRIPTION</H2><PRE>
34 The <B>border</B>, <B>wborder</B> and <B>box</B> routines draw a box around the
35 edges of a window. The argument <I>ls</I> is a character and
36 attributes used for the left side of the border, <I>rs</I> -
37 right side, <I>ts</I> - top side, <I>bs</I> - bottom side, <I>tl</I> - top
38 left-hand corner, <I>tr</I> - top right-hand corner, <I>bl</I> - bottom
39 left-hand corner, and <I>br</I> - bottom right-hand corner. If
40 any of these arguments is zero, then the following default
41 values (defined in <B>curses.h</B>) are used instead: <B>ACS_VLINE</B>,
42 <B>ACS_VLINE</B>, <B>ACS_HLINE</B>, <B>ACS_HLINE</B>, <B>ACS_ULCORNER</B>,
43 <B>ACS_URCORNER</B>, <B>ACS_LLCORNER</B>, <B>ACS_LRCORNER</B>.
45 <B>box(</B><I>win</I><B>,</B> <I>verch</I><B>,</B> <I>horch</I><B>)</B> is a shorthand for the following
46 call: <B>wborder(</B><I>win</I><B>,</B> <I>verch</I><B>,</B> <I>verch</I><B>,</B> <I>horch</I><B>,</B> <I>horch</I><B>,</B> <B>0,</B> <B>0,</B> <B>0,</B>
49 The <B>hline</B> and <B>whline</B> functions draw a horizontal (left to
50 right) line using <I>ch</I> starting at the current cursor posi-
51 tion in the window. The current cursor position is not
52 changed. The line is at most <I>n</I> characters long, or as
53 many as fit into the window.
55 The <B>vline</B> and <B>wvline</B> functions draw a vertical (top to
56 bottom) line using <I>ch</I> starting at the current cursor posi-
57 tion in the window. The current cursor position is not
58 changed. The line is at most <I>n</I> characters long, or as
59 many as fit into the window.
63 <H2>RETURN VALUE</H2><PRE>
64 All routines return the integer <B>OK</B>. The SVr4.0 manual
65 says "or a non-negative integer if <B>immedok</B> is set", but
66 this appears to be an error.
71 The borders generated by these functions are <I>inside</I> bor-
72 ders (this is also true of SVr4 curses, though the fact is
75 Note that <B>border</B> and <B>box</B> may be macros.
79 <H2>PORTABILITY</H2><PRE>
80 These functions are described in the XSI Curses standard,
81 Issue 4. Additional functions <B>mvhline</B>, <B>mvvline</B>, <B>mvwhline</B>,
82 and <B>mvwvline</B> are described there which this implementation
83 does not yet support. The standard specifies that they
84 return <B>ERR</B> on failure, but specifies no error conditions.
