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,

int box_set(WINDOW *win, const cchar_t *verch, const cchar_t *horch);

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.

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.

ls rs ts bs tl tr bl br win verch horch

On success, these functions return OK. Otherwise, they return ERR.
