NAME
       border, wborder, box, hline, whline, vline, wvline, mvhline, mvwhline, mvvline, mvwvline -
       create 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);
       int mvhline(int y, int x, chtype ch, int n);
       int 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.  Other  than
       the window, each argument is a character with attributes:

	      ls - left side,
	      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 corresponding default values (defined in curs-
       es.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 position 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 position 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.

       X/Open does not define any error conditions.  This implementation returns an error if  the
       window pointer is null.

       Functions  with	a  "mv" prefix first perform a cursor movement using wmove, and return an
       error if the position is outside the window, or if the window pointer is null.

NOTES
       The borders generated by these functions are inside borders (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.  The standard specifies
       that they return ERR on failure, but specifies no error conditions.
