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.

KEYWORDS
