curses_border, border, box, wborder -- curses border drawing routines
Curses Library (libcurses, -lcurses)
border(chtype ls, chtype rs, chtype ts, chtype bs, chtype tl, chtype tr, chtype bl,
box(WINDOW *win, chtype vertical, chtype horizontal);
wborder(WINDOW *win, chtype ls, chtype rs, chtype ts, chtype bs, chtype tl, chtype tr,
chtype bl, chtype br);
These functions draw borders around stdscr or around the specified window.
The border() function draws a border around stdscr using the characters given as arguments
to the function. The ls, rs, ts and bs are the characters used to draw the left, right, top
and bottom sides, respectively. The tl, tr, bl and br are the characters used to draw the
top-left, top-right, bottom-left and bottom-right corners, respectively. If any of the
characters have a text portion that is 0 then a default alternate character set character is
used for that character. Note that even though the text portion of the argument is 0, the
argument can still be used to specify the attributes for that portion of the border. The
following table shows the default characters for each argument:
wborder() is the same as border() excepting that the border is drawn around the specified
The box() command draws a box around the window given in win using the vertical character
for the vertical lines and the horizontal character for the horizontal lines. The corner
characters of this box will be the defaults as described for border() above. Passing char-
acters with text portion that is 0 to box() will result in the same defaults as those for
border() as described above.
Functions returning pointers will return NULL if an error is detected. The functions that
return an int will return one of the following values:
OK The function completed successfully.
ERR An error occurred in the function.
