## SYNOPSIS

           #include
           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.
           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.
