nng_pull - pull protocol

Description

The pull protocol is one half of a pipeline pattern. The other half is the push protocol. In the pipeline pattern, pushers distribute messages to pullers. Each message sent by a pusher will be sent to one of its peer pullers, chosen in a round-robin fashion from the set of connected peers available for receiving. This property makes this pattern useful in load-balancing scenarios. SocketOperations The nng_pull0_open() functions create a puller socket. This socket may be used to receive messages, but is unable to send them. Attempts to send messages will result in NNG_ENOTSUP. When receiving messages, the pull protocol accepts messages as they arrive from peers. If two peers both have a message ready, the order in which messages are handled is undefined. ProtocolVersions Only version 0 of this protocol is supported. (At the time of writing, no other versions of this protocol have been defined.) ProtocolOptions The pull protocol has no protocol-specific options. ProtocolHeaders The pull protocol has no protocol-specific headers.
