Tk_GetJoinStyle(3tk) Tk Library Procedures Tk_GetJoinStyle(3tk) 







Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings
    and join styles








#include <tk.h>

int
Tk_GetJoinStyle(interp, string, joinPtr)

const char *
Tk_NameOfJoinStyle(join)









  
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” - or a unique abbreviation of one.

  
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 does not contain a valid join
    style or an abbreviation of one of these names, then an error message is
    stored in interpreter interp's 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 is not a legal join style, then “unknown join
    style” is returned.
