The UuidCreateSequential function creates a new UUID.
RPCRTAPI RPC_STATUS UuidCreateSequential( UUID *Uuid );
Returns a pointer to the created UUID.
||The call succeeded.|
||The UUID is guaranteed to be unique to this computer only. For more information please see: KB article 981080.|
||Cannot get Ethernet or token-ring hardware address for this computer.|
For security reasons, UuidCreate was modified so that it no longer uses a machine's MAC address to generate UUIDs. UuidCreateSequential was introduced to allow creation of UUIDs using the MAC address of a machine's Ethernet card.
The UuidCreateSequential function returns RPC_S_UUID_LOCAL_ONLY when the originating computer does not have an ethernet/token ring (IEEE 802.x) address. In this case, the generated UUID is a valid identifier, and is guaranteed to be unique among all UUIDs generated on the computer. However, the possibility exists that another computer without an ethernet/token ring address generated the identical UUID. Therefore you should never use this UUID to identify an object that is not strictly local to your computer. Computers with ethernet/token ring addresses generate UUIDs that are guaranteed to be globally unique.
