Arguments: stream
Returns (or sets with setf) a symbol indicating the current style for drawing the vertices of thick polylines and polygons on stream. The possible values are:
:round (the default) :miter :bevel :round rounds off each vertex. :miter extends each vertex to a single point (except where the angle is very small, which would extend the vertex unreasonably far). :bevel flattens each vertex.
In Windows 95/98 (as opposed to NT), the non-default values of line-join will be used only when lines are drawn as part of a "path"; see with-drawing-path.
See also: line-end, with-line-end, with-line-join, begin-drawing-path, end-drawing-path, and with-drawing-path.
Note: incompatible change in release 6.0: in releases prior
to 6.0, when a frame-with-single-child instance
was passed to this operator, the operator was actually applied to the
child (the result of applying frame-child to the
frame-with-single-child instance). In release 6.0, this redirection no
longer occurs. If you intend this operator to apply to the
frame-child, pass that to this operator rather than the parent. This
is a non-backward-compatible-change. See the release notes for more
information.
