	  const cchar_t *wch, int n);
       int vline_set(
	  const cchar_t *wch, int n);
       int wvline_set(
	  WINDOW *win,
	  const cchar_t *wch, int n);
       int mvvline_set(
	  int y, int x,
	  const cchar_t *wch, int n);
       int mvwvline_set(
	  WINDOW *win,
	  int y, int x,
	  const cchar_t *wch, int n);

DESCRIPTION
       The border_set and wborder_set functions draw a border around the edges of the current or specified window.  These functions do not  change
       the cursor position, and do not wrap.

       Other than the window, each argument is a complex 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 curses.h) are used instead:
	      WACS_VLINE,
	      WACS_VLINE,
	      WACS_HLINE,
	      WACS_HLINE,
	      WACS_ULCORNER,
	      WACS_URCORNER,
	      WACS_LLCORNER, and
	      WACS_LRCORNER.

       box_set(win, verch, horch); is a shorthand for the following call:

       wborder_set(win, verch, verch,
	   horch, horch, NULL, NULL, NULL, NULL);

       The  *line_set  functions  use  wch to draw a line starting at the current cursor position in the window.  The line is at most n characters
       long or as many as fit into the window.	The current cursor position is not changed.

       The hline_set, mvhline_set, mvwhline_set, and whline_set functions draw a line proceeding toward the last column of the same line.

       The vline_set, mvvline_set, mvwvline_set, and wvline_set functions draw a line proceeding toward the last line of the window.

NOTES
       Note that border_set, hline_set, mvhline_set, mvvline_set, mvwhline_set, mvwvline_set, and vline_set may be macros.

RETURN VALUE
       Upon successful completion, these functions return OK.  Otherwise, they return ERR.

       Functions using a window parameter return an error if it 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.
