wborder

border(3XCURSES)					  X/Open Curses Library Functions					  border(3XCURSES)

NAME

       border, box, wborder - add a single-byte border to a window

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib 
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

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

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

       int box(WINDOW *win, chtype verch, chtype horch);

DESCRIPTION

       The border() and wborder() functions draw a border around the specified window.	All parameters must be single-byte characters whose rendi-
       tion 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

       wborder(win,
       verch, verch,
       horch, horch, 0, 0, 0,
       0)

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

       ls	       Is the character and rendition used for the left side of the border.

       rs	       Is the character and rendition used for the right side of the border.

       bs	       Is the character and rendition used for the bottom of the border.

       tl	       Is the character and rendition used for the top-left corner of the border.

       tr	       Is the character and rendition used for the top-right corner of the border.

       bl	       Is the character and rendition used for the bottom-left corner of the border.

       br	       Is the character and rendition used for the bottom-right corner of the border.

       win	       Is the pointer to the window in which the border or box is to be drawn.

       verch	       Is the character and rendition used for the left and right columns of the box.

       horch	       Is the character and rendition used for the top and bottom rows of the box.

RETURN VALUES

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