Tk_GetCapStyle, Tk_NameOfCapStyle − translate between strings and cap styles
Tk_GetCapStyle(interp, string, capPtr)
const char *
Interpreter to use for error reporting. String containing name of cap style − one of or − or a unique abbreviation of one. Pointer to location in which to store X cap style corresponding to string. Cap style: one of CapButt, CapProjecting, or CapRound.
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 contain a valid cap style or an abbreviation of one of these names, then an error message is stored in interpreter interp’s 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 is returned.
