You need to use the "box" library call...

box Subroutine
Purpose
Draws borders from single-byte characters and renditions.

Library
Curses Library (libcurses.a)

Syntax
#include <curses.h>
int box(WINDOW *win,
chtype verch,
chtype horch);
Description
The box subroutine draws a border around the edges of the specified window. This subroutine does not advance the cursor position. This subroutine does not perform special character processing or perform wrapping.

The box subroutine (*win, verch, horch) has an effect equivalent to:

wborder(win, verch, verch, horch, horch, 0, 0, 0, 0);
Parameters
horch Specifies the character to draw the horizontal lines of the box. The character must be a 1-column character.
verch Specifies the character to draw the vertical lines of the box. The character must be a 1-column character.
*win Specifies the window to draw the box in or around.

Return Values
Upon successful completion, the box function returns OK. Otherwise, it returns ERR.

Examples
To draw a box around the user-defined window, my_window , using | (pipe) as the vertical character and - (minus sign) as the horizontal character, enter:
WINDOW *my_window;
box(my_window, '|', '-');
To draw a box around my_window using the default characters ACS_VLINE and ACS_HLINE, enter:
WINDOW *my_window;
box(my_window, 0, 0);
Implementation Specifics
This subroutine is part of Base Operating System (BOS) Runtime.

Related Information
The border, box_set, and hline subroutines.
