.SH DESCRIPTION
The \fBborder\fR, \fBwborder\fR and \fBbox\fR routines
Other than the window, each argument is a character with attributes:
.sp
.RS
-\fIls\fR - left side,
+\fIls\fR \- left side,
.br
-\fIrs\fR - right side,
+\fIrs\fR \- right side,
.br
-\fIts\fR - top side,
+\fIts\fR \- top side,
.br
-\fIbs\fR - bottom side,
+\fIbs\fR \- bottom side,
.br
-\fItl\fR - top left-hand corner,
+\fItl\fR \- top left-hand corner,
.br
-\fItr\fR - top right-hand corner,
+\fItr\fR \- top right-hand corner,
.br
-\fIbl\fR - bottom left-hand corner, and
+\fIbl\fR \- bottom left-hand corner, and
.br
-\fIbr\fR - bottom right-hand corner.
+\fIbr\fR \- bottom right-hand corner.
.RE

If any of these arguments is zero, then the corresponding

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

The \fBvline\fR and \fBwvline\fR functions draw a vertical (top to bottom) line

+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.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or 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).
