Data Fields
CGGetBytesProcPtr	getBytes
CGSkipBytesProcPtr	skipBytes

Detailed Description

Callbacks for sequentially accessing data. ‘getBytes’ is called to copy ‘count’ bytes from the provider's data to ‘buffer’. It should return the number of bytes copied, or 0 if there's no more data. ‘skipBytes’ is called to skip ahead in the provider's data by ‘count’ bytes. ‘rewind’ is called to rewind the provider to the beginning of the data. ‘releaseProvider’, if non-NULL, is called when the provider is freed.
