getjoinstl(3Tk)

NAME
     Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join
     styles

SYNOPSIS
     #include <tk.h>

     int
     Tk_GetJoinStyle(interp, string, joinPtr)

     char *
     Tk_NameOfJoinStyle(join)

ARGUMENTS
     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
     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.
