+<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 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.7.html"><em>sub</em></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.7.html"><em>req</em></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 accept 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.
+For example both IPC and TCP transports implement their
+pipes using a 1:1 relationship with a connected operating system 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>
+<div class="sect3">
+<h4 id="raw_mode">Raw Mode</h4>
+<div class="paragraph">
+<p>
+Most applications will use sockets in normal, or <em>cooked</em>, mode.
+This mode provides the full semantics of the protocol.
+For example, <a href="nng_req.7.html"><em>req</em></a> sockets will automatically
+match a reply to a request, and resend requests periodically if no reply
+was received.</p>
+</div>
+<div class="paragraph">
+<p>There are situations, such as with <a href="nng_device.3.html">proxies</a>,
+where it is desirable to bypass these semantics and simply pass messages
+to and from the socket with no extra semantic handling.
+This is possible using <em>raw</em> mode sockets.</p>
+</div>
+<div class="paragraph">
+<p>Raw mode sockets are generally constructed with a different function,
+such as <a href="nng_req_open.3.html"><code>nng_req0_open_raw()</code></a>.
+Using these sockets, the application can simply send and receive messages,
+and is responsible for supplying any additional socket semantics.
+Typically this means that the application will need to inspect message
+headers on incoming messages, and supply them on outgoing messages.</p>

+</li>
+<li>
+<p>The following options (<code>nn_getsockopt</code>) are unsupported:
+<code>NN_SNDPRIO</code>, <code>NN_RCVPRIO</code>, <code>NN_IPV4ONLY</code>.
+The priority options may be supported in the future, when

+<li>
+<p>Access to statistics using this legacy API
+(<a href="nn_get_statistic.3compat.html"><code>nn_get_statistic()</code></a>) is unsupported.</p>
+</li>
+<li>
+<p>Some transports can support longer URLs than legacy <em>libnanomsg</em> can.
+It is a good idea to use short pathnames in URLs if interoperability
+is a concern.</p>
+</li>
+<li>
+<p>Only absolute paths are supported in <code>ipc://</code> URLs.
+For example, <code>ipc:///tmp/mysocket</code> is acceptable, but <code>ipc://mysocket</code> is not.</p>
+</li>
+<li>
+<p>The WebSocket transport in this implementation (<code>ws://</code> URLs)
+only supports BINARY frames.</p>
+</li>
+<li>
+<p>Some newer transports are unusable from this mode.
+In particular, this legacy API offers no way to configure
+TLS or ZeroTier parameters that may be required for use.</p>
+</li>
+<li>
+<p>ABI versioning of the compatibility layer is not supported,
+and the <code>NN_VERSION_</code> macros are not present.</p>
+</li>
+<li>
+<p>Runtime symbol information is not implemented.
+Specifically, there is no <code>nn_symbol()</code> function yet.
+(This may be addressed later if there is a need.)</p>
+</li>
+<li>
+<p>The TCP transport (<code>tcp://</code> URLs) does not support specifying the local
+address or interface when binding.  (This could be fixed in the future,
+but most likely this will be available only using the new API.)</p>
+</li>
+<li>
+<p>The values of <code>NN_RCVMAXSIZE</code> are constrained.
+Specifically, values set larger than 2GB using the new API will be reported
+as unlimited (<code>-1</code>) in the new API, and the value <code>0</code> will disable any
+enforcement, just like <code>-1</code>.
+(There is no practical reason to ever want to limit the receive size to
+zero.)</p>
+</li>
+<li>
+<p>This implementation counts buffers in terms of messages rather than bytes.
+As a result, the buffer sizes accessed with <code>NN_SNDBUF</code> and <code>NN_RCVBUF</code> are
+rounded up to a whole number of kilobytes, then divided by 1024, in order
+to approximate buffering assuming 1 KB messages.
+Few applications should need to adjust the default values.</p>

+pattern.
+For example, if <em>s1</em> is a <a href="nng_pub.7.html"><em>pub</em></a> socket, then <em>s2</em> must

+In these cases, the default limit (usually 8), ensures that messages will
+self-terminate when they have passed through too many forwarders,
+protecting the network from unlimited message amplification that can arise

+The <code>nng_dialer_get()</code> functions are used to retrieve option values for

+The actual options that may be retrieved in this way
+vary, and many are documented in <a href="nng_options.5.html">nng_options(5)</a>.</p>

+<p>This function is untyped and can be used to retrieve the value of any option.
+The caller must store a pointer to a buffer to receive the value in <em>val</em>,
+and the size of the buffer shall be stored at the location referenced
+by <em>valszp</em>.<br>
+<br>
+When the function returns, the actual size of the data copied (or that
+would have been copied if sufficient space were present) is stored at
+the location referenced by <em>valszp</em>.
+If the caller&#8217;s buffer is not large
+enough to hold the entire object, then the copy is truncated.
+Therefore the caller should validate that the returned size in <em>valszp</em> does not
+exceed the original buffer size to check for truncation.<br>
+<br>
+It is acceptable to pass <code>NULL</code> for <em>val</em> if the value in <em>valszp</em> is zero.
+This can be used to determine the size of the buffer needed to receive
+the object.</p>

+<p>These functions provide support for managing tables of data based on
+identifiers, ensuring that identifiers are allocated uniquely and within
+specified range limits.</p>
+</div>
+<div class="paragraph">
+<p>The table stores data pointers (which must not be <code>NULL</code>) at a logical numeric index.
+It does so efficiently, even if large gaps exist, and it provides a means to efficiently
+allocate a numeric identifier from a pool of unused identifiers.</p>
+</div>
+<div class="paragraph">
+<p>Identifiers are allocated in increasing order, without reusing old identifiers until the
+largest possible identifier is allocated.  After wrapping, only identifiers that are no longer
+in use will be considered.
+No effort to order the availability of identifiers based on when they were freed is made.</p>
+</div>
+<div class="paragraph">
+<p>An initial table is allocated with <code>nng_id_map_alloc()</code>, which takes the lowest legal identifier in <em>lo</em>,
+and the largest legal identifier in <em>hi</em>.
+The new table is returned in <em>map_p</em>, and should be used as the <em>map</em> argument to the rest of these functions.</p>
+</div>

+<div class="content">
+<div class="paragraph">
+<p>As a special convenience, if these are specified as zero, then a full range of 32-bit identifiers is assumed.

+exact values desired.</p>
+</div>
+</div>
+</div>
+<div class="paragraph">
+<p>The <em>flags</em> argument is a bit mask of flags for the table.
+If <code>NNG_MAP_RANDOM</code> is specified, then the starting point for allocations is randomized, but subsequent allocations will then be monotonically increasing.
+This is useful to reduce the odds of different instances of an application using the same identifiers at the same time.</p>
+</div>
+<div class="paragraph">
+<p>The <code>nng_id_get()</code> function returns the value previously stored with the given identifier.
+If no value is currently associated with the identifer, it returns <code>NULL</code>.</p>

+<p>The <code>nng_id_set()</code> function sets the value with the associated identifier.
+This can be used to replace a previously allocated identifier.

+This function does not necessarily honor the identifier range limits set for the map when it was allocated.</p>

+<div class="paragraph">
+<p>The <code>nng_opts_parse()</code> is function is a supplemental function intended to
+facilitate parsing command line arguments.
+This function exists largely to stand in for <code>getopt()</code> from POSIX
+systems, but it is available everywhere that <em>NNG</em> is, and it includes
+some capabilities missing from <code>getopt()</code>.</p>
+</div>
+<div class="paragraph">
+<p>The function parses arguments from <code>main()</code> (using <em>argc</em> and <em>argv</em>),
+starting at the index referenced by <em>idx</em>.
+(New invocations typically set the value pointed to by <em>idx</em> to 1.)</p>
+</div>
+<div class="paragraph">
+<p>Options are parsed as specified by <em>spec</em> (see <a href="#_option_specification">Option Specification</a>.)
+The value of the parsed option will be stored at the address indicated by
+<em>val</em>, and the value of <em>idx</em> will be incremented to reflect the next
+option to parse.</p>

+<td class="icon">
+<i class="fa icon-tip" title="Tip"></i>

+For using this to parse command-line like strings that do not include
+the command name itself, set the value referenced by <em>idx</em> to zero
+instead of one.
+</td>
+</tr>
+</table>
+</div>
+<div class="paragraph">
+<p>If the option had an argument, a pointer to that is returned at the address
+referenced by <em>arg</em>.</p>
+</div>
+<div class="paragraph">
+<p>This function should be called repeatedly, until it returns either -1
+(indicating the end of options is reached) or a non-zero error code is
+returned.</p>
+</div>
+<div class="sect2">
+<h3 id="_option_specification">Option Specification</h3>
+<div class="paragraph">
+<p>The calling program must first create an array of <code>nng_optspec</code> structures
+describing the options to be supported.
+This structure has the following members:</p>
+</div>
+<div class="dlist">
+<dl>
+<dt class="hdlist1"><code>o_name</code></dt>
+<dd>
+<p>The long style name for the option, such as "verbose".
+This will be parsed on the command line when it is prefixed with two dashes.
+It may be <code>NULL</code> if only a short option is to be supported.</p>
+</dd>
+<dt class="hdlist1"><code>o_short</code></dt>
+<dd>
+<p>This is a single letter (at present only ASCII letters are supported).
+These options appear as just a single letter, and are prefixed with a single dash on the command line.
+The use of a slash in lieu of the dash is <em>not</em> supported, in order to avoid confusion with path name arguments.
+This value may be set to 0 if no short option is needed.</p>
+</dd>
+<dt class="hdlist1"><code>o_val</code></dt>
+<dd>
+<p>This is a numeric value that is unique to this option.
+This value is assigned by the application program, and must be non-zero
+for a valid option.
+If this is zero, then it indicates the end of the specifications, and the
+rest of this structure is ignored.
+The value will be returned to the caller in <em>val</em> by <code>nng_opts_parse()</code> when
+this option is parsed from the command line.</p>
+</dd>
+<dt class="hdlist1"><code>o_arg</code></dt>
+<dd>
+<p>This value should be set to <code>true</code> if the option should take an argument.</p>
+</dd>
+</dl>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_long_options">Long Options</h3>
+<div class="paragraph">
+<p>Long options are parsed from the <em>argv</em> array, and are indicated when
+the element being scanned starts with two dashes.
+For example, the "verbose" option would be specified as <code>--verbose</code> on
+the command line.
+If a long option takes an argument, it can either immediately follow
+the option as the next element in <em>argv</em>, or it can be appended to
+the option, separated from the option by an equals sign (<code>=</code>) or a
+colon (<code>:</code>).</p>
+</div>
+</div>
+<div class="sect2">
+<h3 id="_short_options">Short Options</h3>
+<div class="paragraph">
+<p>Short options appear by themselves in an <em>argv</em> element, prefixed by a
+dash (<code>-</code>).
+If the short option takes an argument, it can either be appended in the
+same element of <em>argv</em>, or may appear in the next <em>argv</em> element.</p>

+The <code>nng_pipe_get()</code> functions are used to retrieve option values for

+The actual options that may be retrieved in this way
+vary, and many are documented in <a href="nng_options.5.html">nng_options(5)</a>.
+Additionally some transport-specific options and protocol-specific options are
+documented with the transports and protocols themselves.</p>

+A pointer to a buffer to receive the value in <em>val</em>, and the size of the
+buffer shall be stored at the location referenced by <em>valszp</em>.<br>
+<br>
+When the function returns, the actual size of the data copied (or that
+would have been copied if sufficient space were present) is stored at
+the location referenced by <em>valszp</em>.
+If the caller&#8217;s buffer is not large enough to hold the entire object,
+then the copy is truncated.
+Therefore the caller should check for truncation by verifying that the
+size returned in <em>valszp</em> does not exceed the original buffer size.<br>
+<br>
+It is acceptable to pass <code>NULL</code> for <em>val</em> if the value in <em>valszp</em> is zero.
+This can be used to determine the size of the buffer needed to receive
+the object.</p>

+(For example, with a <a href="nng_pub.7.html"><em>pub</em></a> socket the data is broadcast, so that
+any peers who have a suitable subscription will be able to receive it using
+<a href="nng_recv.3.html"><code>nng_recv()</code></a> or a similar function.)
+Furthermore, some protocols may not support sending (such as
+<a href="nng_sub.7.html"><em>sub</em></a>) or may require other conditions.

+<p>
+The <em>ws</em> transport provides communication support between
+peers 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">

+<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 <a href="nng_ws_register.3.html"><code>nng_ws_register()</code></a>.</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

+<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>A URI may be restricted to IPv6 using the scheme <code>ws6://</code> or <code>wss6://</code>, and may
