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.
