CURSES_BORDER(3) | Library Functions Manual | CURSES_BORDER(3)

# NAME

`curses_border`, `border`, `box`, `wborder` —
curses border drawing routines

# LIBRARY

Curses Library (libcurses, -lcurses)

# SYNOPSIS

`#include <curses.h>`

int
`border`(chtype ls, chtype rs, chtype ts, chtype bs, chtype tl, chtype tr, chtype bl, chtype br);

int
`box`(WINDOW *win, chtype vertical, chtype horizontal);

int
`wborder`(WINDOW *win, chtype ls, chtype rs, chtype ts, chtype bs, chtype tl, chtype tr, chtype bl, chtype br);

# DESCRIPTION

These functions draw borders around `stdscr` or around the specified window.

The `border`() function draws a border around `stdscr` using the characters given as arguments to the function. The ls, rs, ts and bs are the characters used to draw the left, right, top and bottom sides, respectively. The tl, tr, bl and br are the characters used to draw the top-left, top-right, bottom-left and bottom-right corners, respectively. If any of the characters have a text portion that is 0 then a default alternate character set character is used for that character. Note that even though the text portion of the argument is 0, the argument can still be used to specify the attributes for that portion of the border. The following table shows the default characters for each argument:

ls | ACS_VLINE
rs | ACS_VLINE
ts | ACS_HLINE
bs | ACS_HLINE
tl | ACS_ULCORNER
tr | ACS_URCORNER
bl | ACS_LLCORNER
br | ACS_LRCORNER

`wborder`() is the same as `border`() excepting that the border is drawn around the specified window.

The `box`() command draws a box around the window given in win using the vertical character for the vertical lines and the horizontal character for the horizontal lines. The corner characters of this box will be the defaults as described for `border`() above. Passing characters with text portion that is 0 to `box`() will result in the same defaults as those for `border`() as described above.

# RETURN VALUES

Functions returning pointers will return `NULL` if an error is detected. The functions that return an int will return one of the following values:

`OK`
  The function completed successfully.
`ERR`
  An error occurred in the function.
