       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.

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  docu-
       mentation 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 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 isn't a legal cap style, then ``unknown cap style'' is returned.

KEYWORDS
       butt, cap style, projecting, round
