curs_border(3X)curs_border(3X)NAME
border, wborder, box, hline, whline, vline, wvline - create curses bor‐
ders, horizontal and vertical lines
SYNOPSIS
#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);
mvhline(int y, int x, chtype ch, int n);
mvwhline(WINDOW *, int y, int x, chtype ch, int n);
int mvvline(int y, int x, chtype ch, int n);
int mvwvline(WINDOW *, int y, int x, chtype ch, int n);
DESCRIPTION
The border, wborder and box routines draw a box around the edges of a
window. The argument ls is a character and attributes used for the
left side of the border, rs - right side, ts - top side, bs - bottom
side, tl - top left-hand corner, tr - top right-hand corner, bl - bot‐
tom left-hand corner, and br - bottom right-hand corner. If any of
these arguments is zero, then the following default values (defined in
curses.h) are used 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: wbor‐
der(win, verch, verch, horch, horch, 0, 0, 0, 0).
The hline and whline functions 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 charac‐
ters long, or as many as fit into the window.
The vline and wvline functions 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 charac‐
ters long, or as many as fit into the window.
RETURN VALUE
All routines return the integer OK. The SVr4.0 manual says "or a non-
negative integer if immedok is set", but this appears to be an error.
NOTES
The borders generated by these functions are inside borders (this is
also true of SVr4 curses, though the fact is not documented).
Note that border and box may be macros.
PORTABILITY
These functions are described in the XSI Curses standard, Issue 4.
Additional functions mvhline, mvvline, mvwhline, and mvwvline are
described there which this implementation does not yet support. The
standard specifies that they return ERR on failure, but specifies no
error conditions.
