.SH DESCRIPTION
The \fBborder\fR, \fBwborder\fR and \fBbox\fR routines
draw a box around the edges of a window.
Other than the window, each argument is a character with attributes:
.sp
.RS
\fIls\fR - left side,
.br
\fIrs\fR - right side,
.br
\fIts\fR - top side,
.br
\fIbs\fR - bottom side,
.br
\fItl\fR - top left-hand corner,
.br
\fItr\fR - top right-hand corner,
.br
\fIbl\fR - bottom left-hand corner, and
.br
\fIbr\fR - bottom right-hand corner.
.RE
.PP
If any of these arguments is zero, then the corresponding
default values (defined in \fBcurses.h\fR) are used instead:
.sp
.RS
\fBACS_VLINE\fR,
.br
\fBACS_VLINE\fR,
.br
\fBACS_HLINE\fR,
.br
\fBACS_HLINE\fR,
.br
\fBACS_ULCORNER\fR,
.br
\fBACS_URCORNER\fR,
.br
\fBACS_LLCORNER\fR,
.br
\fBACS_LRCORNER\fR.
.RE
.PP
\fBbox(\fR\fIwin\fR\fB, \fR\fIverch\fR\fB, \fR\fIhorch\fR\fB)\fR is a shorthand
for the following call: \fBwborder(\fR\fIwin\fR\fB,\fR \fIverch\fR\fB,\fR
\fIverch\fR\fB,\fR \fIhorch\fR\fB,\fR \fIhorch\fR\fB, 0, 0, 0, 0)\fR.
.PP
The \fBhline\fR and \fBwhline\fR functions draw a horizontal (left to right)
line using \fIch\fR starting at the current cursor position in the window.  The
current cursor position is not changed.  The line is at most \fIn\fR characters
long, or as many as fit into the window.
.PP
The \fBvline\fR and \fBwvline\fR functions draw a vertical (top to bottom) line
using \fIch\fR starting at the current cursor position in the window.  The
current cursor position is not changed.  The line is at most \fIn\fR characters
long, or as many as fit into the window.
.SH RETURN VALUE
All routines return the integer \fBOK\fR.  The SVr4.0 manual says "or a
non-negative integer if \fBimmedok\fR is set", but this appears to be an error.
.PP
X/Open does not define any error conditions.
This implementation returns an error
if the window pointer is null.
.SH NOTES
The borders generated by these functions are \fIinside\fR borders (this
is also true of SVr4 curses, though the fact is not documented).
.PP
Note that \fBborder\fR and \fBbox\fR may be macros.
.SH PORTABILITY
These functions are described in the XSI Curses standard, Issue 4.
The standard specifies that they return \fBERR\fR on failure,
but specifies no error conditions.
