FSEntityIdentifier
A base type that identifies containers and volumes.
Declaration
class FSEntityIdentifierOverview
An FSEntityIdentifier is a UUID to identify a container or volume, optionally with eight bytes of qualifying (differentiating) data. You use the qualifiers in cases in which a file server can receive multiple connections from the same client, which differ by user credentials. In this case, the identifier for each client is the server’s base UUID, and a unique qualifier that differs by client.
