NAME

       border,  wborder,  box, hline, whline, vline, wvline, mvh-
       line, mvwhline, mvvline, mvwvline - create curses borders,

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.
