Tk_GetJoinStyle, Tk_NameOfJoinStyle − translate between strings and join styles
#include <tk.h>
int 
Tk_GetJoinStyle(interp, string,
joinPtr)
char * 
Tk_NameOfJoinStyle(join)
| 
 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.  | 
_________________________________________________________________
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.
