CURSES_BORDER(3)        NetBSD 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 win-
     dow.

     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 char-
     acters 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 charac-
     ter 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 ta-
     ble 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.
