status.i4.v = wn_border_width_c(width.i4.v)

	This routine sets the border width for closed objects drawn by the
	"wn_xxx" graphical routines (circles, rectangles, arcs, etc).

	width		width of border in pixels
			(If a value of CLIB_DEFAULT_ARG is passed for this
			argument, the present border width will simply be
			returned to the caller.)

	This function returns status values as follows:

	CBS_INVARG		invalid width
	otherwise		previous border width setting

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	wn_box(_c), wn_circle(_c), wn_circular_arc_c, intro_graphics_windows

	C/C++ usage:

	int	status;
	int	width = 1;

	status = wn_border_width_c(width);
