CURS_BORDER(3CURSES) Curses Library Functions CURS_BORDER(3CURSES)

curs_border, border, wborder, box, whline, wvline - create curses borders, horizontal and vertical lines

cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h>
int border(chtype ls, chtype rs, chtype ts, chtype bs, chtype tl,

chtype tr, chtype bl,chtype br);

int wborder(WINDOW *win, chtype ls, chtype rs, chtype ts,

chtype bs, chtype tl, chtype tr, chtype bl, chtype br);

int box(WINDOW *win, chtype verch, chtype horch);

int hline(chtype ch, int n);

int whline(WINDOW *win, chtype ch, int n);

int vline(chtype ch, int n);

int wvline(WINDOW *win, chtype ch, int n);

With the border(), wborder(), and box() routines, a border is drawn around the edges of the window. The arguments and attributes are:

ls left side of the border
rs right side of the border
ts top side of the border
bs bottom side of the border
tl top left-hand corner
tr top right-hand corner
bl bottom left-hand corner
br bottom right-hand corner

If any of these arguments is zero, then the following default values (defined in <curses.h>) are used respectively instead: ACS_VLINE, ACS_VLINE, ACS_HLINE, ACS_HLINE, ACS_ULCORNER, ACS_URCORNER, ACS_BLCORNER, ACS_BRCORNER.

box(win, verch, horch) is a shorthand for the following call:

wborder(win, verch, verch, horch, horch , 0, 0, 0, 0)

hline() and whline() draw a horizontal (left to right) line using ch starting at the current cursor position in the window. The current cursor position is not changed. The line is at most n characters long, or as many as fit into the window.

vline() and wvline() draw a vertical (top to bottom) line using ch starting at the current cursor position in the window. The current cursor position is not changed. The line is at most n characters long, or as many as fit into the window.

All routines return the integer OK, or a non-negative integer if immedok() is set. See curs_outopts(3CURSES).

See attributes(7) for descriptions of the following attributes:

The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.

Note that border() and box() may be macros.
