<h1>vorbis_analysis_wrote</h1>
<p><i>declared in "vorbis/codec.h";</i></p>
<p>This function tells the encoder new data is available for compression.
Call this after writing new audio into the buffer array returned by
vorbis_analysis_buffer().
</p>
<p>
Call with the <i>vals</i> parameter set to zero to signal the end
of the input data.

<h3>Parameters</h3>
<dl>
<dt><i>v</i></dt>
<dd>Pointer to the vorbis_dsp_state representing the encoder.</dd>
<dt><i>vals</i></dt>
<dd>Number of samples successfully written. This must be less than
or equal to the value passed to vorbis_analysis_buffer(). A value
of zero means all input data has been provided and the compressed
stream should be finalized.</dd>
</dl>
<h3>Return Values</h3>
<ul>
<li>0 for success</li>
<li>negative values for failure:
<ul>
<li>OV_EINVAL - Invalid request; e.g. vals overflows the allocated space.</li>
<li>OV_EFAULT - Internal fault; indicates a bug or memory corruption.</li>
<li>OV_EIMPL - Unimplemented; not supported by this version of the library.</li>
</ul>
