create curses borders, horizontal and vertical lines 

Curses Function


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);

mvhline(int y, int x, chtype ch, int n);

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. The argument ls is a character and attributes used for the left side of the border, 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 following default values (defined in curses.h) are used instead: ACS_VLINE, ACS_VLINE, ACS_HLINE, ACS_HLINE, ACS_ULCORNER, ACS_URCORNER, ACS_BLCORNER, ACS_BRCORNER.

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 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.

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 VALUES

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.


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. Additional functions mvhline(), mvvline(), mvwhline(), and mvwvline() are described there which this implementation does not yet support. The standard specifies that they return ERR on failure, but specifies no error conditions.
