Eiffel does not have the notion of "return", but "Result". A consequence of this is that Eiffel routines are Single-entry-Single-exit, which means less bugs. In the example (below), the Result is of type BOOLEAN.
Moreover, strings in Eiffel are objects and cannot be directly passed to the Windows OS. As such, they need to undergo a format change through the facilities of a WEL_STRING, which makes the appropriate structure conversion.
