Returns the pointer value for the specified {@code parameterName}.
<p>
This method should also be used for integer parameters that may be 32 or
64 bits (e.g. {@code size_t}).

@param object the object to query
@param arg an object argument
@param parameterName the parameter to query

@return the parameter's pointer value
