DESCRIPTION

       Tk_GetJoinStyle places in *joinPtr the X join style corre-
       sponding to string, which will be one of JoinBevel,  Join-
       Miter,  or JoinRound.  Join styles are typically used in X
       graphics contexts to indicate how adjacent  line  segments
       should  be  joined  together.  See the X documentation for
       information on what each style implies.

       Under normal circumstances the return value is TCL_OK  and
       interp  is unused.  If string doesn't contain a valid join
       style or an abbreviation of one of these  names,  then  an
       error  message  is  stored in interp->result, TCL_ERROR is
       returned, and *joinPtr is unmodified.

       Tk_NameOfJoinStyle   is    the    logical    inverse    of
       Tk_GetJoinStyle.   Given a join style such as JoinBevel it
       returns a  statically-allocated  string  corresponding  to
       join.   If  join  isn't a legal join style, then ``unknown
