Structure to receive the properties of the document
Returns
0 on success, or -1 if there are no more documents to return
Description
Pointer to a function that will return information about a the next document in the data source.
Remarks
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.
