Creates a GUID, a unique 128-bit integer used for CLSIDs and interface identifiers.HRESULT CoCreateGuid(
GUID *pguid //Pointer to the GUID on return
);
Parameter
pguid
[out] Pointer to the requested GUID on return.
Return Value
S_OK
The GUID was successfully created.
Win32 errors are returned byUuidCreate but wrapped as an HRESULT.Res
The CoCreateGuid function calls the RPC function UuidCreate, which creates a GUID, a globally unique 128-bit integer. Use the CoCreateGuid function when you need an absolutely unique number that you will use as a persistent identifier in a distributed environment.To a very high degree of certainty, this function returns a unique value – no other invocation, on the same or any other system (networked or not), should return the same value.QuickInfo
