Member Function Documentation

bool AutoOggChainGranuleSeekTable::acceptOggPage (  OggPage *  inOggPage  )  [virtual]
 

All callers to acceptOggPage give away their pointer to this function. All methods implementing this interface are responsible for deleting this page. All callers should NULL their pointer immediately after calling to avoid reusing them.

Implements IOggCallback.
