  73        The <STRONG>border</STRONG>, <STRONG>wborder</STRONG> and <STRONG>box</STRONG> routines draw a box around the
  74        edges of a window.  Other than the window,  each  argument
  75        is a character with attributes:
  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
  87        default values (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
  99        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>
 100        <STRONG>0)</STRONG>.
 101
 102        The <STRONG>hline</STRONG> and <STRONG>whline</STRONG> functions draw a horizontal (left  to
 103        right)  line using <EM>ch</EM> starting at the current cursor posi-
 104        tion in the window.  The current cursor  position  is  not
 105        changed.   The  line  is  at most <EM>n</EM> characters long, or as
 106        many as fit into the window.
 107
 108        The <STRONG>vline</STRONG> and <STRONG>wvline</STRONG> functions draw  a  vertical  (top  to
 109        bottom) line using <EM>ch</EM> starting at the current cursor posi-
 110        tion in the window.  The current cursor  position  is  not
 111        changed.   The  line  is  at most <EM>n</EM> characters long, or as
 112        many as fit into the window.
 113

 115 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
 116        All routines return the integer  <STRONG>OK</STRONG>.   The  SVr4.0  manual
 117        says  "or  a  non-negative integer if <STRONG>immedok</STRONG> is set", but
 118        this appears to be an error.
 119
 120        X/Open does not define any error conditions.  This  imple-
 121        mentation returns an error if the window pointer is null.
 122
 123        Functions  with a "mv" prefix first perform a cursor move-
 124        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
 125        outside the window, or if the window pointer is null.

 129        The  borders  generated by these functions are <EM>inside</EM> bor-
 130        ders (this is also true of SVr4 curses, though the fact is
 131        not documented).
 132
 133        Note that <STRONG>border</STRONG> and <STRONG>box</STRONG> may be macros.

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