Tk_GetJoinStyle(3)	     Tk	Library	Procedures	    Tk_GetJoinStyle(3)

______________________________________________________________________________

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  report-
					 ing.

       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, Join-
					 Miter,	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	 adja-
       cent  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 un-
       used.  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-_re-
       sult, 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 "un-
       known join style" is returned.
