NAME
       border,  wborder, box, hline, whline, vline, wvline - cre-
       ate curses borders, horizontal and vertical lines

SYNOPSIS
       #include <curses.h>
       int border(chtype ls, chtype rs, chtype ts, chtype bs,
          chtype tl, chtype tr, chtype bl, chtype br);
       int wborder(WINDOW *win, chtype ls, chtype rs,
          chtype ts, chtype bs, chtype tl, chtype tr,
          chtype bl, chtype br);
       int box(WINDOW *win, chtype verch, chtype horch);
       int hline(chtype ch, int n);
       int whline(WINDOW *win, chtype ch, int n);
       int vline(chtype ch, int n);
       int wvline(WINDOW *win, chtype ch, int n);
       mvhline(int y, int x, chtype ch, int n);
       mvwhline(WINDOW *, int y, int x, chtype ch, int n);
       int mvvline(int y, int x, chtype ch, int n);
       int mvwvline(WINDOW *, int y, int x, chtype ch, int n);

DESCRIPTION
       The border, wborder and box routines draw a box around the
       edges  of  a  window.   The argument ls is a character and
       attributes used for the left side  of  the  border,  rs  -
       right  side,  ts  -  top  side, bs - bottom side, tl - top
       left-hand corner, tr - top right-hand corner, bl -  bottom
       left-hand  corner,  and br - bottom right-hand corner.  If
       any of these arguments is zero, then the following default
       values  (defined in curses.h) are used instead: ACS_VLINE,
       ACS_VLINE,     ACS_HLINE,     ACS_HLINE,     ACS_ULCORNER,
       ACS_URCORNER, ACS_LLCORNER, ACS_LRCORNER.

       box(win,  verch,  horch)  is a shorthand for the following
       call: wborder(win, verch, verch, horch, horch,  0,  0,  0,
       0).

       The  hline and whline functions draw a horizontal (left to
       right) line using ch starting at the current cursor  posi-
       tion  in  the  window.  The current cursor position is not
       changed.  The line is at most n  characters  long,  or  as
       many as fit into the window.

       The  vline  and  wvline  functions draw a vertical (top to
       bottom) line using ch starting at the current cursor posi-
       tion  in  the  window.  The current cursor position is not
       changed.  The line is at most n  characters  long,  or  as
       many as fit into the window.

RETURN VALUE
       All  routines  return  the  integer OK.  The SVr4.0 manual
       says "or a non-negative integer if immedok  is  set",  but
       this appears to be an error.

NOTES
       The  borders  generated by these functions are inside bor-
       ders (this is also true of SVr4 curses, though the fact is
       not documented).

       Note that border and box may be macros.

PORTABILITY
       These  functions are described in the XSI Curses standard,
       Issue 4.  Additional functions mvhline, mvvline, mvwhline,
       and mvwvline are described there which this implementation
       does not yet support.  The standard  specifies  that  they
       return  ERR on failure, but specifies no error conditions.
