  73        The  <STRONG>border</STRONG>,  <STRONG>wborder</STRONG> and <STRONG>box</STRONG> routines draw a box around the edges of a
  74        window.  Other than the window, each argument is a character  with  at-
  75        tributes:
  76
  77               <EM>ls</EM> - left side,
  78               <EM>rs</EM> - right side,
  79               <EM>ts</EM> - top side,
  80               <EM>bs</EM> - bottom side,
  81               <EM>tl</EM> - top left-hand corner,
  82               <EM>tr</EM> - top right-hand corner,
  83               <EM>bl</EM> - bottom left-hand corner, and
  84               <EM>br</EM> - bottom right-hand corner.
  85
  86        If  any of these arguments is zero, then the corresponding default val-
  87        ues (defined in <STRONG>curses.h</STRONG>) are used instead:
  88
  89               <STRONG>ACS_VLINE</STRONG>,
  90               <STRONG>ACS_VLINE</STRONG>,
  91               <STRONG>ACS_HLINE</STRONG>,
  92               <STRONG>ACS_HLINE</STRONG>,
  93               <STRONG>ACS_ULCORNER</STRONG>,
  94               <STRONG>ACS_URCORNER</STRONG>,
  95               <STRONG>ACS_LLCORNER</STRONG>,
  96               <STRONG>ACS_LRCORNER</STRONG>.
  97
  98        <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>wbor-</STRONG>
  99        <STRONG>der(</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>.
 100
 101        The  <STRONG>hline</STRONG>  and <STRONG>whline</STRONG> functions draw a horizontal (left to right) line
 102        using <EM>ch</EM> starting at the current cursor position in  the  window.   The
 103        current  cursor position is not changed.  The line is at most <EM>n</EM> charac-
 104        ters long, or as many as fit into the window.
 105
 106        The <STRONG>vline</STRONG> and <STRONG>wvline</STRONG> functions draw a vertical (top to bottom) line us-
 107        ing <EM>ch</EM> starting at the current cursor position in the window.  The cur-
 108        rent cursor position is not changed.  The line is at most <EM>n</EM>  characters
 109        long, or as many as fit into the window.
 110
 111
 112 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
 113        All  routines return the integer <STRONG>OK</STRONG>.  The SVr4.0 manual says "or a non-
 114        negative integer if <STRONG>immedok</STRONG> is set", but this appears to be an error.
 115
 116        X/Open does not define any error conditions.  This  implementation  re-
 117        turns an error if the window pointer is null.
 118
 119        Functions  with  a  "mv"  prefix  first perform a cursor movement using
 120        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
 121        the window pointer is null.

 125        The  borders  generated  by these functions are <EM>inside</EM> borders (this is
 126        also true of SVr4 curses, though the fact is not documented).
 127
 128        Note that <STRONG>border</STRONG> and <STRONG>box</STRONG> may be macros.

 132        These functions are described in the XSI Curses standard, Issue 4.  The
 133        standard  specifies  that  they return <STRONG>ERR</STRONG> on failure, but specifies no
 134        error conditions.
