The <STRONG>border</STRONG>, <STRONG>wborder</STRONG> and <STRONG>box</STRONG> routines draw a box around the edges of a
window. Other than the window, each argument is a character with at-
tributes:
<EM>ls</EM> - left side,
<EM>rs</EM> - right side,
<EM>ts</EM> - top side,
<EM>bs</EM> - bottom side,
<EM>tl</EM> - top left-hand corner,
<EM>tr</EM> - top right-hand corner,
<EM>bl</EM> - bottom left-hand corner, and
<EM>br</EM> - bottom right-hand corner.
If any of these arguments is zero, then the corresponding default val-
ues (defined in <STRONG>curses.h</STRONG>) are used instead:
<STRONG>ACS_VLINE</STRONG>,
<STRONG>ACS_VLINE</STRONG>,
<STRONG>ACS_HLINE</STRONG>,
<STRONG>ACS_HLINE</STRONG>,
<STRONG>ACS_ULCORNER</STRONG>,
<STRONG>ACS_URCORNER</STRONG>,
<STRONG>ACS_LLCORNER</STRONG>,
<STRONG>ACS_LRCORNER</STRONG>.
<STRONG>box(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>)</STRONG> is a shorthand for the following call: <STRONG>wbor-</STRONG>
<STRONG>der(</STRONG><EM>win</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>verch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <EM>horch</EM><STRONG>,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG> <STRONG>0,</STRONG> <STRONG>0)</STRONG>.
The <STRONG>hline</STRONG> and <STRONG>whline</STRONG> functions draw a horizontal (left to right) line
using <EM>ch</EM> starting at the current cursor position in the window. The
current cursor position is not changed. The line is at most <EM>n</EM> charac-
ters long, or as many as fit into the window.
The <STRONG>vline</STRONG> and <STRONG>wvline</STRONG> functions draw a vertical (top to bottom) line us-
ing <EM>ch</EM> starting at the current cursor position in the window. The cur-
rent cursor position is not changed. The line is at most <EM>n</EM> characters
long, or as many as fit into the window.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
All routines return the integer <STRONG>OK</STRONG>. The SVr4.0 manual says "or a non-
negative integer if <STRONG>immedok</STRONG> is set", but this appears to be an error.
X/Open does not define any error conditions. This implementation re-
turns an error if the window pointer is null.
Functions with a "mv" prefix first perform a cursor movement using
<STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
the window pointer is null.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
The borders generated by these functions are <EM>inside</EM> borders (this is
also true of SVr4 curses, though the fact is not documented).
Note that <STRONG>border</STRONG> and <STRONG>box</STRONG> may be macros.

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