Synopsis

cc [options] file -lcurses
#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 *bl, const cchar_t *br);

Description

The border_set(CURSES) and wborder_set(CURSES) 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 spacing complex characters with renditions, which have the following uses in drawing the border:

Arg Usage Default 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 a null pointer, 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.
