Description

With the border(), wborder(), and box() routines, a border is drawn around the edges of the window. The arguments and attributes are:
lsleft side of the border
rsright side of the border
tstop side of the border
bsbottom side of the border
tltop left-hand corner
trtop right-hand corner
blbottom left-hand corner
brbottom 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.

Return Values

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

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