Tk_GetJoinStyle(3) Tk Library Procedures Tk_GetJoinStyle(3)
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles
Tk_GetJoinStyle(interp, string, joinPtr)
const char *
Tcl_Interp *interp (in) Interpreter to use for error reporting.
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 cor-
responding to string.
int join (in) 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 doc-
umentation for information on what each style implies.
Under normal circumstances the return value is TCL_OK and interp is unused. If string
does not 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 unmodi-
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 is not
a legal join style, then "unknown join style" is returned.
