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
       unused.	 If  string doesn't contain a valid join style or an abbrevia-
       tion 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 join style'' is returned.
