hi [ref] means that the parameter has a value on it before going into the function. The called function can read and or change tvalue any time. The parameter goes in then comes out [out] means that the parameter has no official value before going into the function. The called function must initialize it. The parameter only goes out For more reference : Click Here T hank You
