<p>The <code xref="mongoc_stream_read">mongoc_stream_write()</code> function shall perform a write to a <code xref="mongoc_stream_t">mongoc_stream_t</code>. It's modeled on the API and semantics of <code>write()</code>, though the parameters map only loosely.</p>
</section>
<section id="return">
<title>Returns</title>
<p>The <code xref="mongoc_stream_write">mongoc_stream_write</code> function returns the number of bytes write on success. It returns <code>>= 0</code> and <code>< min_bytes</code> when end-of-file is encountered and <code>-1</code> on failure. <code>errno</code> is set upon failure.</p>
