You can add packets to the Oggz packet queue only when it is "hungry" by providing an OggzHungry callback.

An OggzHungry callback will:

- Create an ogg_packet structure
- Add it to the packet queue with oggz_write_feed()

Once you have set such a callback with oggz_write_set_hungry_callback(), simply call oggz_write() or oggz_write_output() repeatedly, and Oggz will call your callback to provide packets when it is hungry.

This process is illustrated in the following diagram:

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