+<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>
