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.

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 prefixed with “mv” first perform cursor movement and fail if the position (y, x) is outside the
       window boundaries.

NOTES

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

PORTABILITY

       These functions are described in X/Open Curses, Issue 4.
