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  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

       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 the XSI Curses standard, Issue 4.
