SYNOPSIS
#include

int
border
(chtype ls,
chtype rs, chtype ts,
chtype bs, chtype tl,
chtype tr, chtype bl,
chtype br);
int

(WINDOW
*win, chtype
vertical, chtype

DESCRIPTION
These functions draw borders aroundstdscr
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:
ls | ACS_VLINE |
rs | ACS_VLINE |
ts | ACS_HLINE |
bs | ACS_HLINE |
tl | ACS_ULCORNER |
tr | ACS_URCORNER |
bl | ACS_LLCORNER |
br | ACS_LRCORNER |
wborder
()
is the same as border
() excepting that the border is
drawn around the specified window.
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 characters with text portion
that is 0 to box
() will result in the same defaults
as those for border
() as described above.
RETURN VALUES
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.
