border, wborder - draw borders from single-byte characters and renditions
#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);
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:
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.
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
Upon successful completion, these functions return OK. Otherwise, they return ERR.
No errors are defined.
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.
