NAME
       Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap styles

SYNOPSIS
       #include <tk.h>

       int
       Tk_GetCapStyle(interp, string, capPtr)

       const char *
       Tk_NameOfCapStyle(cap)

ARGUMENTS
       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".

       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.

DESCRIPTION
       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  con-tain contain
       tain  a  valid cap style or an abbreviation of one of these names, then an error message is stored in
       interp->result, TCL_ERROR is returned, and *capPtr is unmodified.

       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.
