Description

The border_set() and wborder_set() functions draw a border around the specified window. All parameters must be spacing complex characters with renditions. A parameter which is a null pointer is replaced by the default character.

Constant Values for Borders

The call

box_set(win,
verch, horch)

is a short form for

wborder(win,
verch, verch,
horch, horch, NULL,
NULL, NULL, NULL)

When the window is boxed, the bottom and top rows and right and left columns are unavailable for text.
