       Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap styles


       #include <tk.h>

       Tk_GetCapStyle(interp, string, capPtr)

       const char *


       Tcl_Interp *interp (in)          Interpreter to use for error reporting.

       const char *string (in)          String  containing  name  of  cap  style - one of “butt”,
                                        “projecting”, or “round” - or a  unique  abbreviation  of

       int *capPtr (out)                Pointer  to  location  in  which  to  store  X  cap style
                                        corresponding to string.

       int cap (in)                     Cap style: one of CapButt, CapProjecting, or CapRound.


       Tk_GetCapStyle places in *capPtr the X cap style corresponding to string.   This  will  be
       one of the values CapButt, CapProjecting, or CapRound.  Cap styles are typically used in X
       graphics contexts to indicate how the end-points of lines should be  capped.   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 cap 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 *capPtr is

       Tk_NameOfCapStyle is the logical inverse of Tk_GetCapStyle.  Given a  cap  style  such  as
       CapButt  it  returns  a statically-allocated string corresponding to cap.  If cap is not a
       legal cap style, then “unknown cap style” is returned.
