Tk_GetCapStyle, Tk_NameOfCapStyle - translate between strings and cap styles
Tk_GetCapStyle(interp, string, capPtr)
Tcl_Interp *interp (in) Interpreter to use for error reporting.
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 staticallyallocated string corresponding to cap. If cap isn't a legal cap style, then ``unknown cap style'' is returned.
