DESCRIPTION

     Tk_GetJoinStyle  places  in  *joinPtr  the  X   join   style
     corresponding  to  string,  which  will be one of JoinBevel,
     JoinMiter, 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 does not 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.
