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 at-
tributes:
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 val-
ues (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, mvwh-
line_set, mvwvline_set, and vline_set may be macros.
PORTABILITY
These functions are described in X/Open Curses, Issue 4.
