<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p>The <em>zmq_msg_copy()</em> function shall copy the message object referenced by <em>src</em>
to the message object referenced by <em>dest</em>. The original content of <em>dest</em>, if
any, shall be released.</p></div>

<td class="icon">
<div class="title">Caution</div>
</td>
<td class="content">The implementation may choose not to physically copy the message
content, rather to share the underlying buffer between <em>src</em> and <em>dest</em>. Avoid
modifying message content after a message has been copied with
<em>zmq_msg_copy()</em>, doing so can result in undefined behaviour. If what you need
is an actual hard copy, allocate a new message using <em>zmq_msg_init_size()</em> and
copy the message content using <em>memcpy()</em>.</td>
