Subject: RubyCocoa and addresses of pointers

Some methods in Objective-C require the address of a pointer, so the method
can fill in the value of the pointer. How do I do this in RubyCocoa?

As an example, here's some Objective-C code

    // fpDate is an IB outlet
    NSDateFormatter *dateFormatter = [fpDate formatter];
    NSCalendarDate *templateDate;
    BOOL conversionResult;
    NSString *error;
    BOOL conversionResult;

    conversionResult = [dateFormatter getObjectValue:&templateDate
					   forString:[fpDate stringValue]
				    errorDescription:&error];

getObjectValue:forString:errorDescription: takes two arguments that are
addresses of pointers. The method returns objects in those parameters.

Is there a way to do this in RubyCocoa?
