Description |

0 on success, or -1 if there are no more documents to return
The data source implementation should ensure that string pointers in the dtsDataSourceFileInfo remain valid until the next getNextDocInfo call. Following a getNextDocInfo call, the dtSearch Engine may either call getCurrentDoc to get the document contents, or it may call getNextDocInfo again to get the next document.
