<h1>vorbis_analysis_blockout</h1>

<p><i>declared in "vorbis/codec.h";</i></p>

<p>This fuction examines the available uncompressed data and tries to
break it into appropriate sized blocks. It should be called in a loop
after adding new data with vorbis_analysis_buffer()/vorbis_analysis_wrote()
until it returns zero (need more data) or an negative value (error).
</p>
<p>
Each block returned should be passed to vorbis_analysis() for transform
and coding.
</p>

<h3>Parameters</h3>
<dl>
<dt><i>v</i></dt>
<dd>Pointer to the vorbis_dsp_state representing the encoder.</dd>
<dt><i>vb</i></dt>
<dd>Pointer to a previously initialized vorbis_block object to hold the
returned data.
</dl>


<h3>Return Values</h3>
<ul>
<li>1 for success when more blocks are available.</li>
<li>0 for success when this is the last block available from the current input.</li>
<li>negative values for failure:
<ul>
<li>OV_EINVAL - Invalid parameters.</li>
<li>OV_EFAULT - Internal fault; indicates a bug or memory corruption.</li>
