<h1>Writing with OggzHungry callbacks</h1>An OggzHungry callback will:<ul>
<li>Create an <em>ogg_packet</em> structure</li><li>Add it to the packet queue with <a class="el" href="group__write__api.html#g6ccaceb107db1fd2eae047dbdbaa5889" title="Add a packet to oggz's packet queue.">oggz_write_feed()</a></li></ul>
<p>
Once you have set such a callback with <a class="el" href="group__write__api.html#gf362c030bc7a7f57cb23f2b863a59389" title="Set a callback for Oggz to call when oggz is hungry .">oggz_write_set_hungry_callback()</a>, simply call <a class="el" href="group__write__api.html#g3c97d94ea425d64546adf9c368b71904" title="Write n bytes from an OGGZ handle.">oggz_write()</a> or <a class="el" href="group__write__api.html#g5606dff01964caec4582eb172fde0c1c" title="Output data from an OGGZ handle.">oggz_write_output()</a> repeatedly, and Oggz will call your callback to provide packets when it is hungry.<p>
This process is illustrated in the following diagram:<p>

The following example code generates a stream of ten packets, each containing a single byte ('A', 'B', ... , 'J'):<p>
