curs_border(3X)                                                                              curs_border(3X)



NAME
       border, wborder, box, hline, whline, vline, wvline, mvhline, mvwhline, mvvline, mvwvline - create
       curses borders, horizontal and vertical lines

SYNOPSIS
       #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);
       int hline(chtype ch, int n);
       int whline(WINDOW *win, chtype ch, int n);
       int vline(chtype ch, int n);
       int wvline(WINDOW *win, chtype ch, int n);
       int mvhline(int y, int x, chtype ch, int n);
       int mvwhline(WINDOW *, int y, int x, chtype ch, int n);
       int mvvline(int y, int x, chtype ch, int n);
       int mvwvline(WINDOW *, int y, int x, chtype ch, int n);

DESCRIPTION
       The border, wborder and box routines draw a box around the edges of a window.  Other than the window,
       each argument is a character with attributes:

              ls - left side,
              rs - right side,
              ts - top side,
              bs - bottom side,
              tl - top left-hand corner,
              tr - top right-hand corner,
              bl - bottom left-hand corner, and
              br - bottom right-hand corner.

       If  any  of  these arguments is zero, then the corresponding default values (defined in curses.h) are
       used instead:

              ACS_VLINE,
              ACS_VLINE,
              ACS_HLINE,
              ACS_HLINE,
              ACS_ULCORNER,
              ACS_URCORNER,
              ACS_LLCORNER,
              ACS_LRCORNER.

       box(win, verch, horch) is a shorthand for the  following  call:  wborder(win,  verch,  verch,  horch,
       horch, 0, 0, 0, 0).

       The  hline  and whline functions draw a horizontal (left to right) line using ch starting at the cur-rent current
       rent cursor position in the window.  The current cursor position is not changed.  The line is at most
       n characters long, or as many as fit into the window.

       The  vline and wvline functions draw a vertical (top to bottom) line using ch starting at the current
       cursor position in the window.  The current cursor position is not changed.  The line is  at  most  n
       characters long, or as many as fit into the window.

RETURN VALUE
       All  routines return the integer OK.  The SVr4.0 manual says "or a non-negative integer if immedok is
       set", but this appears to be an error.

       X/Open does not define any error conditions.  This implementation returns  an  error  if  the  window
       pointer is null.

NOTES
       The borders generated by these functions are inside borders (this is also true of SVr4 curses, though
       the fact is not documented).

       Note that border and box may be macros.

PORTABILITY
       These functions are described in the XSI Curses standard, Issue 4.  The standard specifies that  they
       return ERR on failure, but specifies no error conditions.
