NAME

       nng_pull - pull protocol

SYNOPSIS

           #include <nng/protocol/pipeline0/pull.h>

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.

   Socket Operations
       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.

   Protocol Versions
       Only version 0 of this protocol is supported. (At the time of writing, no other versions of this protocol
       have been defined.)

   Protocol Options
       The pull protocol has no protocol-specific options.

   Protocol Headers
       The pull protocol has no protocol-specific headers.
