REGISTER command exists or not?

[JoseFMP]

In the description of the TCP protocol there is nothing like a REGISTER command:
https://nsq.io/clients/tcp_protocol_spec.html

However, the go-nsq library has a function to create a REGISTER command describing it as being used to register a channel/topic into nsq. nsq.Register(..., ...)

Does this command exists or not?

• If it does not exists, why is it present in go-nsq library?
• If it exists, is not working. Nsq complains: - E_INVALID invalid command REGISTER what makes sense since this command is not described in the protocol spec.

REGISTER is only used between nsqd and nsqlookupd, not between consumer clients and nsqd

Thank you so much. Clear then.
