Question: <socket>.identity= under LibZMQ.version3? #79

Closed mistergibson closed 11 years ago

Regarding: https://github.com/chuckremes/ffi-rzmq/blob/master/lib/ffi-rzmq/socket.rb Line 535

I understand that LibZMQ version 3 uses unsigned 16-bit integer for identity instead of a uuid-as-string. Should this line be altered to cast .to_i, or does it pack in a string (of numerals) of the integer? Some clarification would be appreciated.

Thanks

0mq uses an integer for its internally-generated identities only. The man page says that you can override the identity with your own identity up to 255 bytes long. In Ruby, dealing with strings is far easier than dealing with packed bytes.
