+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng</em> library provides a common messaging framework intended to
+solve common communication problems in distributed applications.
+It offers a number of <em>protocols</em>, and also a number of <em>transports</em>.</p>
+</div>
+<div class="paragraph">
+<p>The <em>protocols</em> implement the semantics associated with particular
+communications scenarios, such as RPC style services, service discovery,
+publish/subscribe, and so forth.</p>
+</div>
+<div class="paragraph">
+<p>The <em>transports</em> provide support for underlying transport methods, such
+as TCP, IPC, websockets, and so forth.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng</em> library is designed to permit easy creation of new <em>transports</em> and,
+to a lesser extent, new <em>protocols</em>.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng</em> library is wire compatible with the SP protocols described in
+the nanomsg project; projects using
+<a href="https://github.com/nanomsg/nanomsg"><em>libnanomsg</em></a> can inter-operate with
+nng as well as other conforming implementations.  (One such implementation
+is <a href="https://github.com/go-mangos/mangos"><em>mangos</em></a>.)  Applications using <em>nng</em>
+which wish to communicate with older libraries must ensure that they only
+use protocols or transports offered by the earlier library.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng</em> library also offers a compatible API, permitting legacy code to
+be recompiled or relinked against <em>nng</em>.  When doing this, support for
+certain enhancements or features will likely be absent, requiring the
+application developer to use the new-style API.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng</em> library is implemented in pure C; if you need bindings for
+other languages please check the <a href="http://nanomsg.org/">website</a>.</p>

+<h3 id="_conceptual_overview">Conceptual Overview</h3>
+<div class="paragraph">
+<p><em>nng</em> presents a <em>socket</em> view of networking.  The sockets are constructed
+using protocol-specific functions, as a given socket implements precisely
+one <em>nng</em> protocol.</p>
+</div>
+<div class="paragraph">
+<p>Each socket can be used to send and receive messages (if the protocol)
+supports it, and implements the appropriate protocol semantics.  For
+example, <a href="nng_sub.html">nng_sub(7)</a> sockets automatically filter incoming
+messages to discard those for topics that have not been subscribed.</p>
+</div>
+<div class="paragraph">
+<p><em>nng</em> sockets are message oriented, so that messages are either delivered
+wholly, or not at all.  Partial delivery is not possible.  Furthermore,
+<em>nng</em> does not provide any other delivery or ordering guarantees;
+messages may be dropped or reordered.  (Some protocols, such as
+<a href="nng_req.html">nng_req(7)</a> may offer stronger guarantees by
+performing their own retry and validation schemes.)</p>
+</div>
+<div class="paragraph">
+<p>Each socket can have zero, one, or many "endpoints", which are either
+<em>listeners</em> or <em>dialers</em>. (A given socket may freely choose whether it uses
+listeners, dialers, or both.)  These "endpoints" provide access to
+underlying transports, such as TCP, etc.</p>
+</div>
+<div class="paragraph">
+<p>Each endpoint is associated with a URL, which is a service address.  For
+dialers, this will be the service address that will be contacted, whereas
+for listeners this is where the listener will bind and watch for new
+connections.</p>
+</div>
+<div class="paragraph">
+<p>Endpoints do not themselves transport data.  They are instead responsible
+for the creation of <em>pipes</em>, which can be thought of as message-oriented,
+connected, streams.  Pipes frequently correspond to a single underlying
+byte stream&#8201;&#8212;&#8201;for example both IPC and TCP transports implement their
+pipes using a 1:1 relationship with a connected socket.</p>
+</div>
+<div class="paragraph">
+<p>Endpoints create pipes as needed.  Listeners will create them when a new
+client connection request arrives, and dialers will generally create one,
+then wait for it to disconnect before reconnecting.</p>
+</div>
+<div class="paragraph">
+<p>Most applications should not have to worry about endpoints or pipes at
+all; the socket abstraction should provide all the functionality needed
+other than in a few specific circumstances.</p>

+<div class="paragraph">
+<p>The <em>nng_bus</em> protocol provides for building mesh networks where
+every peer is connected to every other peer.  In this protocol,
+each message sent by a node is sent to every one of its directly
+connected peers.</p>

+Messages are only sent to directly connected peers.  This means
+that in the event that a peer is connected indirectly, it will not
+receive messages.  When using this protocol to build mesh networks, it
+is therefore important that a <em>fully-connected</em> mesh network be
+constructed.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>All message delivery in this pattern is best-effort, which means that
+peers may not receive messages. Furthermore, delivery may occur to some,
+all, or none of the directly connected peers. (Messages are not delivered
+when peer nodes are unable to receive.)  Hence, send operations will never
+block; instead if the message cannot be delivered for any reason it is
+discarded.</p>

+In order to minimize the likelihood of message loss, this protocol
+should not be used for high throughput communications.  Furthermore, the
+more traffic <em>in aggregate</em> that occurs across the topology, the more
+likely that message loss is to occur.

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_inproc</em> transport provides communication support between
+<em>nng</em> sockets within the same process. This may be used as an alternative
+to slower transports when data must be moved within the same process.</p>
+</div>
+<div class="paragraph">
+<p>This transport tries hard to avoid copying data, and thus is very
+light-weight.</p>
+</div>
+<div class="sect2">
+<h3 id="_registration">Registration</h3>
+<div class="paragraph">
+<p>The <em>inproc</em> transport is generally built-in to the <em>nng</em> core, so
+no extra steps to use it should be necessary.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_uri_format">URI Format</h3>
+<div class="paragraph">
+<p>This transport uses URIs using the scheme <code>inproc://</code>, followed by
+an arbitrary string of text, terminated by a <code>NUL</code> byte.  The
+entire URI must be less than <code>NNG_MAXADDRLEN</code> bytes long.</p>
+</div>
+<div class="paragraph">
+<p>Multiple URIs can be used within the
+same application, and they will not interfere with one another.</p>
+</div>
+<div class="paragraph">
+<p>Two applications may also use the same URI without interfering with each
+other, and they will be unable to communicate with each other using
+that URI.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_socket_address">Socket Address</h3>
+<div class="paragraph">
+<p>When using an <code>nng_sockaddr</code> structure, the actual structure is of type

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_ipc</em> transport provides communication support between
+<em>nng</em> sockets within different processes on the same host. For POSIX
+platforms, this is implemented using UNIX domain sockets.  For Windows,
+this is implemented using Windows Named Pipes.  Other platforms may
+have different implementation strategies.</p>
+</div>
+<div class="sect2">
+<h3 id="_registration">Registration</h3>
+<div class="paragraph">
+<p>The <em>ipc</em> transport is generally built-in to the <em>nng</em> core, so
+no extra steps to use it should be necessary.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_uri_format">URI Format</h3>
+<div class="paragraph">
+<p>This transport uses URIs using the scheme <code>ipc://</code>, followed by
+a path name in the file system where the socket or named pipe
+should be created.</p>
+</div>
+<div class="admonitionblock tip">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>
+</td>
+<td class="content">
+On Windows, all names are prefixed by <code>\.\pipe\</code> and do not
+occupy the normal file system.  On POSIX platforms, the path is
+taken literally, and is relative to the current directory, unless
+an extra leading <code>/</code> is provided.  For example, <code>ipc://myname</code> refers
+to the name <code>myname</code> in the current directory, whereas <code>ipc:///tmp/myname</code>
+refers to <code>myname</code> located in <code>/tmp</code>.

+<div class="paragraph">
+<p>Normally pair sockets are for one-to-one communication, and a given peer
+will reject new connections if it already has an active connection to another
+peer.</p>
+</div>
+<div class="paragraph">
+<p>In <em>polyamorous</em> mode, which is only available with version 1, a socket can
+support many one-to-one connections.  In this mode, the application must
+choose the remote peer to receive an ougoing message by setting the value
+of the pipe ID on the outgoing message using
+the <a href="nng_msg_set_pipe.html">nng_msg_set_pipe(3)</a> function.</p>
+</div>
+<div class="paragraph">
+<p>Most often the value of the outgoing pipe ID will be obtained from an incoming
+message using the <a href="nng_msg_get_pipe.html">nng_msg_get_pipe(3)</a> function,
+such as when replying to an incoming message.</p>
+</div>
+<div class="paragraph">
+<p>In order to prevent head-of-line blocking, if the peer on the given pipe
+is not able to receive (or the pipe is no longer available, such as if the
+peer has disconnected), then the message will be discarded with no notification
+to the sender.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The following protocol-specific options are available.</p>

+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>NNG_OPT_PAIR1_POLY</code></dt>
+<dd>
+<p>(Version 1 only).  This option enables the use of <em>polyamorous</em> mode.
+The value is read-write, and takes an integer boolean value.  The default
+false value (0) indicates that legacy monogamous mode should be used.</p>
+</dd>
+<dt class="hdlist1"><code>NNG_OPT_MAXTTL</code></dt>
+<dd>
+<p>(Version 1 only).  Maximum time-to-live.  This option is an integer value
+between 0 and 255,
+inclusive, and is the maximum number of "hops" that a message may
+pass through until it is discarded.  The default value is 8.  A value
+of 0 may be used to disable the loop protection, allowing an infinite
+number of hops.</p>

+Each node along a forwarding path may have it&#8217;s own value for the
+maximum time-to-live, and performs its own checks before forwarding a message.

+<div class="paragraph">
+<p>Version 1 of the pair protocol uses a single 32-bit unsigned value.  The
+low-order (big-endian) byte of this value contains a "hop" count, and is
+used in conjuction with the <code>NNG_OPT_MAXTTL</code> option to guard against
+device forwarding loops.  This value is initialized to 1, and incremented
+each time the message is received by a new node.</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_pub</em> protocol is one half of a publisher/subscriber pattern.
+In this pattern, a publisher sends data, which is broadcast to all
+subscribers.  The subscribing applications only see the data to which
+they have subscribed.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng_pub</em> protocol is the publisher side, and the
+<a href="nng_sub.html">nng_sub(7)</a> protocol is the subscriber side.</p>
+</div>
+<div class="admonitionblock note">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-note" title="Note"></i>
+</td>
+<td class="content">
+In this implementation, the publisher delivers all messages to all
+subscribers. The subscribers maintain their own subscriptions, and filter
+them locally.  Thus, this pattern should not be used in an attempt to
+reduce bandwidth consumption.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The topics that subscribers subscribe to is just the first part of
+the message body.  Applications should construct their messages
+accordingly.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_pub0_open()</code> call creates a publisher socket.  This socket
+may be used to send messages, but is unable to receive them.  Attempts
+to receive messages will result in <code>NNG_ENOTSUP</code>.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.)</p>
+</div>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_pull</em> protocol is one half of a pipeline pattern. The other half
+is the <a href="nng_push.html">nng_push(7)</a> protocol.</p>
+</div>
+<div class="paragraph">
+<p>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.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_pull0_open()</code> 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 <code>NNG_ENOTSUP</code>.</p>
+</div>
+<div class="paragraph">
+<p>When receiving messages, the <em>nng_pull</em> 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.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The <em>nng_pull</em> protocol has no protocol-specific options.</p>
+</div>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_push</em> protocol is one half of a pipeline pattern.  The
+other side is the <a href="nng_pull.html">nng_pull(7)</a> protocol.</p>
+</div>
+<div class="paragraph">
+<p>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.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_push0_open()</code> call creates a pusher socket.  This socket
+may be used to send messages, but is unable to receive them.  Attempts
+to receive messages will result in <code>NNG_ENOTSUP</code>.</p>
+</div>
+<div class="paragraph">
+<p>Send operations will observe flow control (back-pressure), so that
+only peers capable of accepting a message will be considered.  If no
+peer is available to receive a message, then the send operation will
+wait until one is available, or the operation times out.</p>
+</div>
+<div class="admonitionblock note">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-note" title="Note"></i>
+</td>
+<td class="content">
+Although the pipeline protocol honors flow control, and attempts
+to avoid dropping messages, no guarantee of delivery is made.  Furthermore,
+as there is no capability for message acknowledgement, applications that
+need reliable delivery are encouraged to consider the
+<a href="nng_req.html">nng_req(7)</a> protocol instead.

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_rep</em> protocol is one half of a request/reply pattern.
+In this pattern, a requester sends a message to one replier, who
+is expected to reply.  The request is resent if no reply arrives,
+until a reply is received or the request times out.</p>
+</div>
+<div class="admonitionblock tip">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>
+</td>
+<td class="content">
+This protocol is useful in setting up RPC-like services.  It
+is also "reliable", in that a the requester will keep retrying until
+a reply is received.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The <em>nng_rep</em> protocol is the replier side, and the
+<a href="nng_req.html">nng_req(7)</a> protocol is the requester side.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_rep0_open()</code> call creates a requester socket.  This socket
+may be used to receive messages (requests), and then to send replies.  Generally
+a reply can only be sent after receiving a request.  (Attempts to receive
+a message will result in <code>NNG_ESTATE</code> if there is no outstanding request.)</p>
+</div>
+<div class="paragraph">
+<p>Attempts to send on a socket with no outstanding requests will result
+in <code>NNG_ESTATE</code>.</p>
+</div>
+<div class="paragraph">
+<p>Raw mode sockets (set with <code>NNG_OPT_RAW</code>) ignore all these restrictions.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The following protocol-specific options are available.</p>
+</div>
+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>NNG_OPT_MAXTTL</code></dt>
+<dd>
+<p>Maximum time-to-live.  This option is an integer value
+between 0 and 255,
+inclusive, and is the maximum number of "hops" that a message may
+pass through until it is discarded.  The default value is 8.  A value
+of 0 may be used to disable the loop protection, allowing an infinite
+number of hops.</p>
+</dd>
+</dl>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_headers">Protocol Headers</h3>
+<div class="paragraph">
+<p>The <em>nng_rep</em> protocol uses a <em>backtrace</em> in the header.  This
+form uses an array of 32-bit big-endian identifiers, where the first
+element in the array
+identifies the local peer identifier to which the message will next be sent.
+This is a hop-by-hop header where each element in a path adds routing
+information to the end when sending a request, and when replying removes
+elements to obtain the next hop information.  The request ID is at the
+end of this header and is inserted into the header as its first element
+by the originating surveyor.  (Request IDs are distinguished from hops by
+having their high order bit set to one.  They are generated automatically
+and randomly when a request is first issued.)</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_req</em> protocol is one half of a request/reply pattern.
+In this pattern, a requester sends a message to one replier, who
+is expected to reply.  The request is resent if no reply arrives,
+until a reply is received or the request times out.</p>
+</div>
+<div class="admonitionblock tip">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>
+</td>
+<td class="content">
+This protocol is useful in setting up RPC-like services.  It
+is also "reliable", in that a the requester will keep retrying until
+a reply is received.
+</td>
+</tr>
+</table>
+</div>
+<div class="admonitionblock note">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-note" title="Note"></i>
+</td>
+<td class="content">
+Because requests are resent, it is important that they be idempotent
+to ensure predictable and repeatable behavior even in the face of duplicated
+requests, which can occur (for example if a reply message is lost for
+some reason.)
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The requester generally only has one outstanding request at a time unless
+in "raw" mode (via <code>NNG_OPT_RAW</code>), and it will generally attempt to spread
+work requests to different peer repliers.</p>

+</div>
+<div class="paragraph">
+<p>The <em>nng_req</em> protocol is the requester side, and the
+<a href="nng_rep.html">nng_rep(7)</a> protocol is the replier side.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_req0_open()</code> call creates a requester socket.  This socket
+may be used to send messages (requests), and then to receive replies.  Generally
+a reply can only be received after sending a request.  (Attempts to receive
+a message will result in <code>NNG_ESTATE</code> if there is no outstanding request.)</p>
+</div>
+<div class="paragraph">
+<p>Requests may be canceled by sending a different request.  This will
+cause the requester to discard any reply from the earlier request,
+but it will not stop a replier
+from processing a request it has already received or terminate a request
+that has already been placed on the wire.</p>
+</div>
+<div class="paragraph">
+<p>Attempts to receive on a socket with no outstanding requests will result
+in <code>NNG_ESTATE</code>.</p>
+</div>
+<div class="paragraph">
+<p>Raw mode sockets (set with <code>NNG_OPT_RAW</code>) ignore all these restrictions.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The following protocol-specific options are available.</p>
+</div>
+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>NNG_OPT_REQ_RESENDTIME</code></dt>
+<dd>
+<p>This read/write option is a duration (32-bit unsigned integer) representing
+a relative number of milliseconds.
+When a new request is started, a timer of this duration is also started.
+If no reply is received before this timer expires, then the request will
+be resent.  (Requests are also automatically resent if the peer to whom
+the original request was sent disconnects, or if a peer becomes available
+while the requester is waiting for an available peer.)</p>
+</dd>
+<dt class="hdlist1"><code>NNG_OPT_MAXTTL</code></dt>
+<dd>
+<p>Maximum time-to-live.  This option is an integer value
+between 0 and 255,
+inclusive, and is the maximum number of "hops" that a message may
+pass through until it is discarded.  The default value is 8.  A value
+of 0 may be used to disable the loop protection, allowing an infinite
+number of hops.</p>
+</dd>
+</dl>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_headers">Protocol Headers</h3>
+<div class="paragraph">
+<p>The <em>nng_req</em> protocol uses a <em>backtrace</em> in the header.  This
+form uses an array of 32-bit big-endian identifiers, where the first
+element in the array
+identifies the local peer identifier to which the message will next be sent.
+This is a hop-by-hop header where each element in a path adds routing
+information to the end when sending a request, and when replying removes
+elements to obtain the next hop information.  The request ID is at the
+end of this header and is inserted into the header as its first element
+by the originating surveyor.  (Request IDs are distinguished from hops by
+having their high order bit set to one.  They are generated automatically
+and randomly when a request is first issued.)</p>

+<h2 id="_description">DESCRIPTION</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_respondent</em> protocol is one half of a survey pattern.
+In this pattern, a surveyor sends a survey, which is broadcast to all
+peer respondents.  The respondents then have a chance to reply (but after
+not obliged to).  The survey itself is a timed event, so that responses
+received after the survey has finished are discarded.</p>
+</div>
+<div class="admonitionblock tip">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>
+</td>
+<td class="content">
+This protocol is useful in solving voting problems, such as leader
+election in cluster configurations, as well as certain kinds of service
+discovery problems.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The <em>nng_respondent</em> protocol is the respondent side, and the
+<a href="nng_surveyor.html">nng_surveyor(7)</a> protocol is the surveyor side.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_respondent0_open()</code> call creates a respondent socket.  This socket
+may be used to receive messages, and then to send replies.  Generally
+a reply can only be sent after receiving a survey, and generally the
+reply will be sent to surveyor from whom the last survey was received.</p>
+</div>
+<div class="paragraph">
+<p>Respondents may discard a survey by simply not replying to it.</p>
+</div>
+<div class="paragraph">
+<p>Raw mode sockets (set with <code>NNG_OPT_RAW</code>) ignore all these restrictions.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.  An earlier and
+incompatible version of the protocol was used in older pre-releases of
+<a href="http://nanomsg.org">nanomsg</a>, but was not released in any production
+version.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The following protocol-specific options are available.</p>
+</div>
+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>NNG_OPT_MAXTTL</code></dt>
+<dd>
+<p>Maximum time-to-live.  This option is an integer value
+between 0 and 255,
+inclusive, and is the maximum number of "hops" that a message may
+pass through until it is discarded.  The default value is 8.  A value
+of 0 may be used to disable the loop protection, allowing an infinite
+number of hops.</p>
+</dd>
+</dl>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_headers">Protocol Headers</h3>
+<div class="paragraph">
+<p>The <em>nng_respondent</em> protocol uses a <em>backtrace</em> in the header.  This
+form uses an array of 32-bit big-endian identifiers, where the first
+element in the array
+identifies the local peer identifier to which the message will next be sent.
+This is a hop-by-hop header where each element in a path adds routing
+information to the end when sending a survey, and when replying removes
+elements to obtain the next hop information.  The survey ID is at the
+end of this header and is inserted into the header as its first element
+by the originating surveyor.  (Survey IDs are distinguished from hops by
+having their high order bit set to one.)</p>

+<div class="paragraph">
+<p>The <em>nng_sub</em> protocol is one half of a publisher/subscriber pattern.
+In this pattern, a publisher sends data, which is broadcast to all
+subscribers.  The subscribing applications only see the data to which
+they have subscribed.</p>
+</div>
+<div class="paragraph">
+<p>The <em>nng_sub</em> protocol is the subscriber side, and the
+<a href="nng_pub.html">nng_pub(7)</a> protocol is the publisher side.</p>
+</div>
+<div class="admonitionblock note">

+<td class="icon">
+<i class="fa icon-note" title="Note"></i>
+</td>
+<td class="content">
+In this implementation, the publisher delivers all messages to all
+subscribers. The subscribers maintain their own subscriptions, and filter
+them locally.  Thus, this pattern should not be used in an attempt to
+reduce bandwidth consumption.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The topics that subscribers subscribe to is just the first part of
+the message body.  Applications should construct their messages
+accordingly.</p>

+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_sub0_open()</code> call creates a subscriber socket.  This socket
+may be used to receive messages, but is unable to send them.  Attempts
+to send messages will result in <code>NNG_ENOTSUP</code>.</p>
+</div>

+<dl>
+<dt class="hdlist1"><code>NNG_OPT_SUB_SUBSCRIBE</code></dt>
+<dd>
+<p>This option registers a topic that the subscriber is interested in.
+The option is write-only, and takes an array of bytes, of arbitrary size.
+Each incoming message is checked against the list of subscribed topics.
+If the body begins with the entire set of bytes in the topic, then the
+message is accepted.  If no topic matches, then the message is
+discarded.</p>

+<h2 id="_description">DESCRIPTION</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_surveyor</em> protocol is one half of a survey pattern.
+In this pattern, a surveyor sends a survey, which is broadcast to all
+peer respondents.  The respondents then have a chance to reply (but after
+not obliged to).  The survey itself is a timed event, so that responses
+received after the survey has finished are discarded.</p>
+</div>
+<div class="admonitionblock tip">
+<table>
+<tr>
+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>
+</td>
+<td class="content">
+This protocol is useful in solving voting problems, such as leader
+election in cluster configurations, as well as certain kinds of service
+discovery problems.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>The <em>nng_surveyor</em> protocol is the surveyor side, and the
+<a href="nng_respondent.html">nng_respondent(7)</a> protocol is the respondent side.</p>
+</div>
+<div class="sect2">
+<h3 id="_socket_operations">Socket Operations</h3>
+<div class="paragraph">
+<p>The <code>nng_surveyor0_open()</code> call creates a respondent socket.  This socket
+may be used to send messages (surveys), and then to receive replies.  Generally
+a reply can only be received after sending a survey. Generally a surveyor
+can expect to receive at most one reply from each responder.  (Messages
+can be duplicated in some topologies, so there is no guarantee of this.)</p>
+</div>
+<div class="paragraph">
+<p>Attempts to receive on a socket with no outstanding survey will result
+in <code>NNG_ESTATE</code>.  If the survey times out while the surveyor is waiting
+for replies, then the result will be <code>NNG_ETIMEDOUT</code>.</p>
+</div>
+<div class="paragraph">
+<p>Only one survey can be outstanding at a time; sending another survey will
+cancel the prior one, and any responses from respondents from the prior
+survey that arrive after this will be discarded.</p>
+</div>
+<div class="paragraph">
+<p>Raw mode sockets (set with <code>NNG_OPT_RAW</code>) ignore all these restrictions.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_versions">Protocol Versions</h3>
+<div class="paragraph">
+<p>Only version 0 of this protocol is supported.  (At the time of writing,
+no other versions of this protocol have been defined.  An earlier and
+incompatible version of the protocol was used in older pre-releases of
+<a href="http://nanomsg.org">nanomsg</a>, but was not released in any production
+version.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_options">Protocol Options</h3>
+<div class="paragraph">
+<p>The following protocol-specific options are available.</p>
+</div>
+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>NNG_OPT_SURVEYOR_SURVEYTIME</code></dt>
+<dd>
+<p>This read/write option is a duration (32-bit unsigned integer) representing
+a relative number of milliseconds that following surveys will last.
+When a new survey is started, a timer of this duration is also started.
+Any responses arriving this time will be discarded.  Attempts to receive
+after the timer expires with no other surveys started will result in
+<code>NNG_ESTATE</code>.  Attempts to receive when this timer expires will result in
+<code>NNG_ETIMEDOUT</code>.</p>
+</dd>
+<dt class="hdlist1"><code>NNG_OPT_MAXTTL</code></dt>
+<dd>
+<p>Maximum time-to-live.  This option is an integer value
+between 0 and 255,
+inclusive, and is the maximum number of "hops" that a message may
+pass through until it is discarded.  The default value is 8.  A value
+of 0 may be used to disable the loop protection, allowing an infinite
+number of hops.</p>
+</dd>
+</dl>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_protocol_headers">Protocol Headers</h3>
+<div class="paragraph">
+<p>The <em>nng_surveyor</em> protocol uses a <em>backtrace</em> in the header.  This
+form uses an array of 32-bit big-endian identifiers, where the first
+element in the array
+identifies the local peer identifier to which the message will next be sent.
+This is a hop-by-hop header where each element in a path adds routing
+information to the end when sending a survey, and when replying removes
+elements to obtain the next hop information.  The survey ID is at the
+end of this header and is inserted into the header as its first element
+by the originating surveyor.  (Survey IDs are distinguished from hops by
+having their high order bit set to one.)</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_tcp</em> transport provides communication support between
+<em>nng</em> sockets across a TCP/IP network.  Both IPv4 and IPv6
+are supported when the underlying platform also supports it.</p>
+</div>
+<div class="sect2">
+<h3 id="_registration">Registration</h3>
+<div class="paragraph">
+<p>The <em>tcp</em> transport is generally built-in to the <em>nng</em> core, so
+no extra steps to use it should be necessary.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_uri_format">URI Format</h3>
+<div class="paragraph">
+<p>This transport uses URIs using the scheme <code>tcp://</code>, followed by
+an IP address or hostname, followed by a colon and finally a
+TCP port number.  For example, to contact port 80 on the localhost
+either of the following URIs could be used: <code>tcp://127.0.0.1:80</code> or
+<code>tcp://localhost:80</code>.</p>
+</div>
+<div class="paragraph">
+<p>When specifying IPv6 addresses, the address must be enclosed in
+square brackets (<code>[]</code>) to avoid confusion with the final colon
+separating the port.</p>
+</div>
+<div class="paragraph">
+<p>For example, the same port 80 on the IPv6 loopback address (<em>::1</em>) would
+be specified as <code>tcp://[::1]:80</code>.</p>

+When using symbolic names, the name is resolved when the
+name is first used. <em>nng</em> won&#8217;t become aware of changes in the
+name resolution until restart,

+<div class="paragraph">
+<p>The special value of 0 (<code>INADDR_ANY</code>) can be used for a listener
+to indicate that it should listen on all interfaces on the host.
+A short-hand for this form is to either omit the address, or specify
+the asterisk (<code>*</code>) character.  For example, the following three
+URIs are all equivalent, and could be used to listen to port 9999
+on the host:</p>

+</li>
+<li>
+<p><code>tcp://:9999</code></p>
+</li>
+</ol>
+</div>
+<div class="paragraph">
+<p>The entire URI must be less than <code>NNG_MAXADDRLEN</code> bytes long.</p>

+<p>When using an <code>nng_sockaddr</code> structure, the actual structure is either
+of type <code>nng_sockaddr_in</code> (for IPv4) or <code>nng_sockaddr_in6</code> (for IPv6).
+These are <code>struct</code> types with the following definitions:</p>

+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_tls</em> transport provides communication support between
+<em>nng</em> sockets across a TCP/IP network using
+<a href="https://tools.ietf.org/html/rfc5246">TLS v1.2</a> on top of
+<a href="https://tools.ietf.org/html/rfc793">TCP</a>.  Both IPv4 and IPv6
+are supported when the underlying platform also supports it.</p>
+</div>
+<div class="paragraph">
+<p>The protocol details are documented in
+<a href="http://nanomsg.org/rfcs/sp-tls-v1.html">TLS Mapping for Scalability Protocols</a>.</p>
+</div>
+<div class="sect2">
+<h3 id="_registration">Registration</h3>
+<div class="paragraph">
+<p>Depending upon how the library was built, it may be necessary to
+register the transport by calling <code>nng_tls_register</code>.  This function
+returns zero on success, or an nng error value if the transport
+cannot be initialized for any reason.</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_availability">Availability</h3>
+<div class="paragraph">
+<p>The <em>tls</em> transport depends on the use of an external library.
+As of this writing, <a href="https://tls.mbed.org/">mbed TLS</a> version 2.0
+or later is required.</p>

+<div class="paragraph">
+<p>This transport uses URIs using the scheme <code>tls+tcp://</code>, followed by
+an IP address or hostname, followed by a colon and finally a
+TCP port number.  For example, to contact port 4433 on the localhost
+either of the following URIs could be used: <code>tls+tcp://127.0.0.1:4433</code> or
+<code>tls+tcp://localhost:4433</code>.</p>
+</div>
+<div class="paragraph">
+<p>When specifying IPv6 addresses, the address must be enclosed in
+square brackets (<code>[]</code>) to avoid confusion with the final colon
+separating the port.</p>
+</div>
+<div class="paragraph">
+<p>For example, the same port 4433 on the IPv6 loopback address (<em>::1</em>) would
+be specified as <code>tls+tcp://[::1]:4433</code>.</p>

+to indicate that it should listen on all interfaces on the host.
+A short-hand for this form is to either omit the address, or specify
+the asterisk (<code>*</code>) character.  For example, the following three
+URIs are all equivalent, and could be used to listen to port 9999
+on the host:</p>

+<h2 id="_description">DESCRIPTION</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p>The <em>nng_ws</em> transport provides communication support between
+<em>nng</em> sockets across a TCP/IP network using
+<a href="https://tools.ietf.org/html/rfc6455">WebSockets</a>.  Both IPv4 and IPv6
+are supported when the underlying platform also supports it.</p>
+</div>
+<div class="paragraph">
+<p>The protocol details are documented in
+<a href="http://nanomsg.org/rfcs/sp-websocket-v1.html">WebSocket Mapping for Scalability Protocols</a>.</p>
+</div>
+<div class="sect2">
+<h3 id="_registration">Registration</h3>
+<div class="paragraph">
+<p>Depending upon how the library was built, it may be necessary to
+register the transport by calling <code>nng_ws_register</code>.  This function
+returns zero on success, or an nng error value if the transport
+cannot be initialized for any reason.</p>
+</div>
+<div class="paragraph">
+<p>If TLS support is enabled in the library, secure WebSockets (over TLS v1.2)
+can be used as well, but the secure transport may have to be registered using
+the <code>nng_wss_register</code> function.  (Note that this function will not be
+present if TLS support was not enabled in the library.)</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_uri_format">URI Format</h3>
+<div class="paragraph">
+<p>This transport uses URIs using the scheme <code>ws://</code>, followed by
+an IP address or hostname, optionally followed by a colon and an
+TCP port number, optionally followed by a path.  (If no port number
+is specified then port 80 is assumed.  If no path is specified then
+a path of <code>/</code> is assumed.)
+For example, the URI <code>ws://localhost/app/pubsub</code> would use
+port 80 on localhost, with the path <code>/app/pubsub</code>.</p>
+</div>
+<div class="paragraph">
+<p>Secure WebSockets (if enabled) use the scheme <code>wss://</code>, and the default
+TCP port number of 443.  Otherwise the format is the same as for regular
+WebSockets.</p>
+</div>
+<div class="paragraph">
+<p>When specifying IPv6 addresses, the address must be enclosed in
+square brackets (<code>[]</code>) to avoid confusion with the final colon
+separating the port.</p>
+</div>
+<div class="paragraph">
+<p>For example, the same path and port on the IPv6 loopback address (<code>::1</code>)
+would be specified as <code>ws://[::1]/app/pubsub</code>.</p>

+A short-hand for this form is to either omit the address, or specify

+URIs are all equivalent, and could be used to listen to port 9999

+<p>Depending upon how the library was built, it may be necessary to

+address (sixteen hexadecimal digits), followed by a <code>/</code> delimiter,
+followed by the node number (ten hexadecimal digits) of the listening
+node, followed by a service or port number (decimal value, up to 24-bits).
+For example, the URI <code>zt://0123456789abdef/fedcba9876:999</code> indicates
+that node fedcba9876 on network 0123456789abcdef listening on port 999.</p>
