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.
NOTES
Note that border_set, hline_set, mvhline_set, mvvline_set, mvwh‐
line_set, mvwvline_set, and vline_set may be macros.
RETURN VALUES
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.
