Positions the filter at the beginning of the next chunk, or at the first chunk if this is the first call to the GetChunk method, and returns a description of the current chunk.
SCODE GetChunk( STAT_CHUNK *pStat );
A pointer to a STAT_CHUNK structure containing a description of the current chunk.
This method can return one of these values.
||The operation was completed successfully.|
||The previous chunk is the last chunk.|
||The next chunk is an embedding and no content filter is available.|
||The next chunk is a link and no content filter is available.|
||Password or other security-related access failure.|
||General access failure.|
If upon return pStat points to a STAT_CHUNK structure with the breakType member equal to CHUNK_NO_BREAK, only the idChunk member will be updated with the new chunk identifier (ID) value. The other members of the STAT_CHUNK structure remain unchanged.
Internal value-type properties (chunks with a CHUNKSTATE enumeration value of CHUNK_VALUE) cannot be concatenated using CHUNK_NO_BREAK. A single word cannot span more than two glued chunks.
Chunk ID zero is invalid.
Before the GetChunk method is called for the first time, there is no current chunk. After an error return code of anything other than FILTER_E_END_OF_CHUNKS the next call to the GetChunk method nevertheless retrieves the next chunk after the unavailable one.
Before returning the results of a call to the GetChunk method on an embedded or linked object, check to make sure that the chunk ID is unique. If not, the implementer must renumber the chunk and keep a mapping of the new chunk ID.
