==========

NAME
----
nn_sync - scalability protocol for synchronising state between components


SYNOPSIS
--------
*#include <nanomsg/nn.h>*

*#include <nanomsg/sync.h>*


DESCRIPTION
-----------
Synchronises a state (one message) on the master with the state on the mirrors.

Socket Types
~~~~~~~~~~~~

NN_MASTER::
    This socket is used to expose the state (one message) to the network. State
    is set using send oprtation. Every such operation overwrites the old state
    by the new state. Receive operation is not implemented on this socket type.
NN_MIRROR::
    This socket is used to mirror the state on the master. The changes of
    the state are delivered to the component by receive operations. Send
    operation is not implemented on this socket type.

Socket Options
~~~~~~~~~~~~~~

No protocol-specific socket options are defined at the moment.
