#include <nng/protocol/pipeline0/pull.h> int nng_pull0_open(nng_socket *s);
The nng_pull protocol is one half of a pipeline pattern. The other half is the nng_push(7) 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.
nng_pull0_open() call creates a puller socket. This socket
may be used to receive messages, but is unable to send them. Attempts
to send messages will result in
When receiving messages, the nng_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.
Only version 0 of this protocol is supported. (At the time of writing, no other versions of this protocol have been defined.)
The nng_pull protocol has no protocol-specific options.
The nng_pull protocol has no protocol-specific headers.
