       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 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  docu-
       mentation 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 abbrevia-
       tion 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.

KEYWORDS

       butt, cap style, projecting, round
