-ZMQ_IDENTITY: Retrieve socket identity
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The 'ZMQ_IDENTITY' option shall retrieve the identity of the specified
-'socket'. Socket identity determines if existing 0MQ infrastructure (_message
-queues_, _forwarding devices_) shall be identified with a specific application
-and persist across multiple runs of the application.
-
-If the socket has no identity, each run of an application is completely
-separate from other runs. However, with identity set the socket shall re-use
-any existing 0MQ infrastructure configured by the previous run(s). Thus the
-application may receive messages that were sent in the meantime, _message
-queue_ limits shall be shared with previous run(s) and so on.
-
-Identity can be at least one byte and at most 255 bytes long. Identities
-starting with binary zero are reserved for use by 0MQ infrastructure.
