                                        ing.

       char         *string   (in)      String  containing  name of cap style:
                                        one of ```butt'',  ``projecting'',  or

       int          *capPtr   (out)     Pointer  to location in which to store

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 cor-
       responding to cap.  If cap isn't a legal cap style, then ``unknown  cap
       style'' is returned.


KEYWORDS
