______________________________________________________________________________

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"
                                         - or a unique abbreviation of one.

       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 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
       interpreter interp's 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.
