/*
 * Some observations that an automated test can't produce:
 * An adapter index is a key for an adapter.  That is, if an index is returned
 * from one API, that same index may be used successfully in another API, as
 * long as the adapter remains present.
 * If the adapter is removed and reinserted, however, the index may change (and
 * indeed it does change on Win2K).
 *
 * The Name field of the IP_ADAPTER_INDEX_MAP entries returned by
 * GetInterfaceInfo is declared as a wide string, but the bytes are actually
 * an ANSI string on some versions of the IP helper API under Win9x.  This was
 * apparently an MS bug, it's corrected in later versions.
 *
 * The DomainName field of FIXED_INFO isn't NULL-terminated on Win98.
