ZMQ::Socket::Dealer

A socket of type ZMQ::Socket::Dealer is an advanced pattern used for extending request/reply sockets. Each message sent is load-balanced among all connected peers, and each message received is fair-queued from all connected peers.

Previously this socket was called ZMQ_XREQ and that name remains available for backwards compatibility.

When a ZMQ::Socket::Dealer socket enters an exceptional state due to having reached the high water mark for all peers, or if there are no peers at all, then any ZMQ::Socket#send operations on the socket shall block until the exceptional state ends or at least one peer becomes available for sending; messages are not discarded.

When a ZMQ::Socket::Dealer socket is connected to a ZMQ::Socket::Rep socket each message sent must consist of an empty message part, the delimiter, followed by one or more body parts.
