Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles
int Tk_GetJoinStyle(interp, string, joinPtr)
char * Tk_NameOfJoinStyle(join)
Interpreter to use for error reporting.
String containing name of join style: one of ``bevel'', ``miter'', or ``round''.
Pointer to location in which to store X join style corresponding to string.
Join style: one of JoinBevel, JoinMiter, JoinRound.
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.
bevel, join style, miter, round
