____________________________________________________________________________________________________________

NAME
       Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles

SYNOPSIS
       #include <tk.h>

       int
       Tk_GetJoinStyle(interp, string, joinPtr)

       const char *
       Tk_NameOfJoinStyle(join)

ARGUMENTS
       Tcl_Interp *interp (in)           Interpreter to use for error reporting.

       const char *string (in)           String  containing  name of join style: one of "bevel", "miter", or
                                         "round".

       int *joinPtr (out)                Pointer to location in which to store X join style corresponding to
                                         string.

       int join (in)                     Join style: one of JoinBevel, JoinMiter, JoinRound.

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  indi-cate indicate
       cate  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  con-tain contain
       tain  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 is not a legal join style,
       then "unknown join style" is returned.
