int border(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
specified window. All parameters must be single-byte characters whose
rendition can be expressed using only constants beginning with ACS_. A
parameter with the value of 0 is replaced by the default value.






Constant Values for Borders
Parameter Default Constant Default Character
verch  ACS_VLINE |
horch  ACS_HLINE -
ls ACS_VLINE |
rs ACS_VLINE |
ts ACS_HLINE -
bs ACS_HLINE -
bl ACS_BLCORNER +
br ACS_BRCORNER +
tl ACS_ULCORNER +
tr ACS_URCORNER +




The call

box(win,
verch, horch)





is a short form for

When the window is boxed, the bottom and top rows and right and left columns
overwrite existing text.
