Tk_GetJoinStyle(3Tk)					  Tk_GetJoinStyle(3Tk)

NAME    [Toc]    [Back]

     Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join
     styles

SYNOPSIS    [Toc]    [Back]

     #include <tk.h>

     int
     Tk_GetJoinStyle(interp, string, joinPtr)

     char *
     Tk_NameOfJoinStyle(join)

ARGUMENTS    [Toc]    [Back]

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

     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    [Toc]    [Back]

     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	doesn't	contain	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 isn't a legal join	style, then ``unknown
     join style'' is returned.
