DESCRIPTIONTk_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 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. KEYWORDSbutt, cap style, projecting, round
