.SH DESCRIPTION
.PP
The
\fBborder_set\fR
and
\fBwborder_set\fR
functions draw a border around the edges of the current or specified window.
These functions do not change the cursor position, and do not wrap.
.PP
Other than the window, each argument is a complex character with attributes:
.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:
.RS
\fBWACS_VLINE\fR,
.br
\fBWACS_VLINE\fR,
.br
\fBWACS_HLINE\fR,
.br
\fBWACS_HLINE\fR,
.br
\fBWACS_ULCORNER\fR,
.br
\fBWACS_URCORNER\fR,
.br
\fBWACS_LLCORNER\fR, and
.br
\fBWACS_LRCORNER\fR.
.RE
.PP
\fBbox_set(\fR\fIwin\fR, \fIverch\fR\fB, \fR\fIhorch\fR\fB);\fR
is a shorthand for the following call:
.PP
\fBwborder_set(\fR\fIwin\fR\fB, \fR\fIverch\fR\fB, \fR\fIverch\fR\fB,\fR
\fIhorch\fR\fB, \fR\fIhorch\fR\fB, NULL, NULL, NULL, NULL);\fR
.PP
The
\fB*line_set\fR
functions use
\fIwch\fR
to draw a line starting at the current cursor position in the window.
The line is at most \fIn\fR characters long or as many as fit into the window.
The current cursor position is not changed.
.PP
The
\fBhline_set\fR,
\fBmvhline_set\fR,
\fBmvwhline_set\fR, and
\fBwhline_set\fR
functions draw a line proceeding toward the last column of the same line.
.PP
The
\fBvline_set\fR,
\fBmvvline_set\fR,
\fBmvwvline_set\fR, and
\fBwvline_set\fR
functions draw a line proceeding toward the last line of the window.
.br
.SH NOTES
.PP
Note that
\fBborder_set\fR,
\fBhline_set\fR,
\fBmvhline_set\fR,
\fBmvvline_set\fR,
\fBmvwhline_set\fR,
\fBmvwvline_set\fR, and
\fBvline_set\fR
may be macros.
.br
.SH RETURN VALUE
.PP
Upon successful completion, these functions return
\fBOK\fR.
Otherwise, they return
\fBERR\fR.
.PP
Functions using a window parameter return an error if it 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.
