<div class="paragraph">
<p>The <code>nng_http_req_copy_data()</code> makes a copy of <em>body</em> (of size <em>size</em>)
and sets the HTTP body for the request <em>req</em> to it.
The copy will be deallocated automatically when <em>req</em> is freed.</p>
</div>
<div class="paragraph">
<p>The copied body data will be automatically sent with the request when it
is sent using <a href="nng_http_conn_write_req.3http.html"><code>nng_http_conn_write_req()</code></a>.</p>
</div>
<div class="paragraph">
<p>This also updates the relevant <code>Content-Length</code> header of <em>req</em>.</p>
