+<p>Every messenger contains a single logical queue of incoming messages and a single logical queue of outgoing messages. The messages in these queues may be destined for, or originate from, a variety of addresses.</p>
+<p>The messenger interface is single-threaded. All methods except one (<a class="el" href="group__messenger.html#gaf5a08242376fa805290966e89a54aa8e">pn_messenger_interrupt()</a>) are intended to be used by one thread at a time.</p>
+<h1>Address Syntax </h1>
+<p>An address has the following form::</p>
+<p>[ amqp[s]:// ] [user[:password]@] domain [/[name]]</p>
+<p>Where domain can be one of::</p>
+<p>host | host:port | ip | ip:port | name</p>
+<p>The following are valid examples of addresses:</p>
+<ul>
+<li>example.org</li>
+<li>example.org:1234</li>
+<li>amqp://example.org</li>
+<li>amqps://example.org</li>

+</ul>
+<h1>Sending & Receiving Messages </h1>
+<p>The messenger API works in conjuction with the <a class="el" href="group__message.html#gad9259fa9271e8844c8e05a7e8978e3b2">pn_message_t</a> API. A <a class="el" href="group__message.html#gad9259fa9271e8844c8e05a7e8978e3b2">pn_message_t</a> is a mutable holder of message content.</p>
+<p>The <a class="el" href="group__messenger.html#gadc93816636d614c8ea2abdeef1b99573">pn_messenger_put()</a> operation copies content from the supplied <a class="el" href="group__message.html#gad9259fa9271e8844c8e05a7e8978e3b2">pn_message_t</a> to the outgoing queue, and may send queued messages if it can do so without blocking. The <a class="el" href="group__messenger.html#gafcdc9ca1e3d1505c5ebfb26cc95fb2bb">pn_messenger_send()</a> operation blocks until it has sent the requested number of messages, or until a timeout interrupts the attempt.</p>
+<p>pn_messenger_t *messenger = pn_messenger(NULL); pn_message_t *message = <a class="el" href="group__message.html#ga29b1ebb0e3d0f4663e679eb92b5dfdb9">pn_message()</a>; char subject[1024]; for (int i = 0; i < 3; i++) { pn_message_set_address(message, "amqp://host/queue"); sprintf(subject, "Hello World! %i", i); pn_message_set_subject(message, subject); pn_messenger_put(messenger, message) pn_messenger_send(messenger);</p>
+<p>Similarly, the <a class="el" href="group__messenger.html#ga6a766d6dfb249b2f2db8de0fc4a73990">pn_messenger_recv()</a> method receives messages into the incoming queue, and may block as it attempts to receive up to the requested number of messages, or until the timeout is reached. It may receive fewer than the requested number. The <a class="el" href="group__messenger.html#ga64d4dbf0f6cec27cd57d86728f43dd83">pn_messenger_get()</a> method pops the eldest message off the incoming queue and copies its content into the supplied <a class="el" href="group__message.html#gad9259fa9271e8844c8e05a7e8978e3b2">pn_message_t</a> object. It will not block.</p>
+<p>pn_messenger_t *messenger = pn_messenger(NULL); pn_message_t *message = <a class="el" href="group__message.html#ga29b1ebb0e3d0f4663e679eb92b5dfdb9">pn_message()</a> pn_messenger_recv(messenger): while (pn_messenger_incoming(messenger) > 0) { pn_messenger_get(messenger, message); printf("%s", message.subject); }</p>
+<p>Output: Hello World 0 Hello World 1 Hello World 2</p>
+<p>The blocking flag allows you to turn off blocking behavior entirely, in which case <a class="el" href="group__messenger.html#gafcdc9ca1e3d1505c5ebfb26cc95fb2bb">pn_messenger_send()</a> and <a class="el" href="group__messenger.html#ga6a766d6dfb249b2f2db8de0fc4a73990">pn_messenger_recv()</a> will do whatever they can without blocking, and then return. You can then look at the number of incoming and outgoing messages to see how much outstanding work still remains.</p>
+<h1>Authentication Mechanims </h1>
+<p>The messenger API authenticates using some specific mechanisms. In prior versions of Proton the only authentication mechanism available was the PLAIN mechanism which transports the user's password over the network unencrypted. The Proton versions 0.10 and newer support other more secure mechanisms which avoid sending the users's password over the network unencrypted. For backwards compatibility the 0.10 version of the messenger API will also allow the use of the unencrypted PLAIN mechanism. From the 0.11 version and onwards you will need to set the flag PN_FLAGS_ALLOW_INSECURE_MECHS to carry on using the unencrypted PLAIN mechanism.</p>
+<p>The code for this looks like:</p>
+<p>... pn_messenger_set_flags(messenger, PN_FLAGS_ALLOW_INSECURE_MECHS); ...</p>
+<p>Note that the use of the PLAIN mechanism over an SSL connection is allowed as the password is not sent unencrypted. </p>
