NAME

border, wborder - draw borders from single-byte characters and renditions

 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);

 DESCRIPTION

The border() and wborder() functions draw a border around the edges of the current or specified window. These functions do not advance the cursor position. These functions do not perform special character processing. These functions do not perform wrapping.

The arguments in the left-hand column of the following table contain single-byte characters with renditions, which have the following uses in drawing the border:

Argument		Default
Name	Usage	Value
ls	Starting-column side	ACS_VLINE
rs	Ending-column side	ACS_VLINE
ts	First-line side	ACS_HLINE
bs	Last-line side	ACS_HLINE
tl	Corner of the first line and the starting column	ACS_ULCORNER
tr	Corner of the first line and the ending column	ACS_URCORNER
bl	Corner of the last line and the starting column	ACS_LLCORNER
br	Corner of the last line and the ending column	ACS_LRCORNER

If the value of any argument in the left-hand column is 0, then the default value in the right-hand column is used. If the value of any argument in the left-hand column is a multi-column character, the results are undefined.

 RETURN VALUE

Upon successful completion, these functions return OK. Otherwise, they return ERR.

 ERRORS

No errors are defined.

 APPLICATION USAGE

These functions are only guaranteed to operate reliably on character sets in which each character fits into a single byte, whose attributes can be expressed using only constants with the A_ prefix.
