Chris@1 17
Chris@1 18 <p><i>declared in "vorbis/codec.h";</i></p>
Chris@1 19
Chris@1 20 <p>This function retrieves buffers containing decoded audio samples, similarly
Chris@1 21 to <a href="vorbis_synthesis_pcmout.html">vorbis_synthesis_pcmout</a>.
Chris@1 22 However, it includes some extra samples extrapolated from the end of
Chris@1 23 the audio, suitable for crosslapping with other blocks. This exists mainly
Chris@1 24 for <a href="../vorbisfile/index.html">libvorbisfile</a> to use for
Chris@1 25 handling chained bitstreams and bitstreams with holes.</p>

Chris@1 39 <dt><i>v</i></dt>
Chris@1 40 <dd>The <a href="vorbis_dsp_state.html">vorbis_dsp_state</a> for the
Chris@1 41 decoder instance.</dd>
Chris@1 42 <dt><i>pcm</i></dt>
Chris@1 43 <dd>A pointer to a float** which will be made to point to an array of
Chris@1 44 pointers to the decoded samples for each channel. The memory is owned
Chris@1 45 by the decoder instance and will be freed when the application continues
Chris@1 46 decoding or destroys the decoder instance. This can be NULL, in which
Chris@1 47 case the return value gives the number of samples that would be returned
Chris@1 48 if this function were called with a non-NULL pointer here.</dd>

Chris@1 53 <blockquote>
Chris@1 54 <li>The number of samples available in the output buffer.</li>
Chris@1 55 <li>0 if no more samples are currently available.</li>
