<h1>ogg_sync_pageout</h1>
|
|
|
|
<p><i>declared in "ogg/ogg.h";</i></p>
|
|
|
|
<p>This function takes the data stored in the buffer of the <a href="ogg_sync_state.html">ogg_sync_state</a> struct and inserts them into an <a href="ogg_page.html">ogg_page</a>.
|
|
|
|
<p>In an actual decoding loop, this function should be called first to ensure that the buffer is cleared. The example code below illustrates a clean reading loop which will fill and output pages.
|
|
<p><b>Caution:</b>This function should be called before reading into the buffer to ensure that data does not remain in the ogg_sync_state struct. Failing to do so may result in a memory leak. See the example code below for details.

<h3>Parameters</h3>
|
|
<dl>
|
|
<dt><i>oy</i></dt>
|
|
<dd>Pointer to a previously declared <a href="ogg_sync_state.html">ogg_sync_state</a> struct. Normally, the internal storage of this struct should be filled with newly read data and verified using <a href="ogg_sync_wrote.html">ogg_sync_wrote</a>.</dd>
|
|
<dt><i>og</i></dt>
|
|
<dd>Pointer to page struct filled by this function.
|
|
</dl>
|

|
<h3>Return Values</h3>
|
|
<blockquote>
|
|
<li>-1 if we were not properly synced and had to skip some bytes.</li>
|
|
<li>
|
|
0 if we need more data to verify a page.</li>
|
|
<li>
|
|
1 if we have a page.</li>
|
|
</blockquote>

<h3>Example Usage</h3>

<pre>
|
|
if (ogg_sync_pageout(&oy, &og) != 1) {
|
|
buffer = ogg_sync_buffer(&oy, 8192);
|
|
bytes = fread(buffer, 1, 8192, stdin);
|
|
ogg_sync_wrote(&oy, bytes);
