curs_border_set(3X) curs_border_set(3X)
border_set, wborder_set, box_set, hline_set, whline_set,
mvhline_set, mvwhline_set, vline_set, wvline_set, mvvline_set,
mvwvline_set - create curses borders or lines using complex
characters and renditions
#include <curses.h>
int border_set(
const cchar_t *ls, const cchar_t *rs,
const cchar_t *ts, const cchar_t *bs,
const cchar_t *tl, const cchar_t *tr,
const cchar_t *bl, const cchar_t *br );
int wborder_set(
WINDOW *win,
const cchar_t *ls, const cchar_t *rs,
const cchar_t *ts, const cchar_t *bs,
const cchar_t *tl, const cchar_t *tr,

const cchar_t *verch,
const cchar_t *horch);
int hline_set(
const cchar_t *wch, int n);
int whline_set(
WINDOW *win,
const cchar_t *wch, int n);
int mvhline_set(
int y, int x,
const cchar_t *wch, int n);
int mvwhline_set(
WINDOW *win,
int y, int x,
const cchar_t *wch, int n);
int vline_set(
const cchar_t *wch, int n);
int wvline_set(
WINDOW *win,
const cchar_t *wch, int n);
int mvvline_set(

const cchar_t *wch, int n);
int mvwvline_set(
WINDOW *win,
int y, int x,
const cchar_t *wch, int n);
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.
Note that border_set, hline_set, mvhline_set, mvvline_set, mvwh‐
line_set, mvwvline_set, and vline_set may be macros.
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.
