<h1>ogg_stream_packetpeek</h1>
<p><i>declared in "ogg/ogg.h";</i></p>
<p>This function attempts to assemble a raw data packet and returns
it without advancing decoding.</p>
<p>In a typical situation, this would be called
speculatively after <a
href="ogg_stream_pagein.html">ogg_stream_pagein()</a> to check
the packet contents before handing it off to a codec for
decompression. To advance page decoding and remove
the packet from the sync structure, call
<a href="ogg_stream_packetout.html">ogg_stream_packetout()</a>.</p>

<h3>Parameters</h3>
<dl>
<dt><i>os</i></dt>
<dd>Pointer to a previously declared
<a href="ogg_stream_state.html">ogg_stream_state</a> struct. Before this
function is called, an <a href="ogg_page.html">ogg_page</a> should be
submitted to the stream using
<a href="ogg_stream_pagein.html">ogg_stream_pagein()</a>.</dd>
<dt><i>op</i></dt>
<dd>Pointer to the next packet available in the bitstream, if
any. A NULL value may be passed in the case of a simple "is there a
packet?" check.</dd>
</dl>
<h3>Return Values</h3>
<blockquote>
<ul>
<li>-1 if there's no packet available due to lost sync or a hole in the data.</li>
<li>0 if there is insufficient data available to complete a packet, or on unrecoverable internal error occurred.</li>
<li>1 if a packet is available.</li>
</ul>
