2830:
2831: In the incremental mode, each time a package arrives, it will be
2832: stored in the temporary file. In addition, if an
2833: incremental_callback function is defined, this function will be
2834: called and handled a copy of the newly received data package.
2835: Finally, if a terminate_callback function is defined, it will be
2836: invoked when the request terminates. The caller of this function

2839:
2840: When the function is called with the SYNC mode, the function will
2841: return only when the requested file has been loaded.
2842: The ASYNC mode will immediately return after setting up the

2845: Notes:
2846: At the end of a succesful request, the urlName string contains the
2847: name of the actually retrieved URL. As a URL can change over the time,
2848: (e.g., be redirected elsewhere), it is advised that the function

2853: - docid Document identifier for the set of objects being
2854: retrieved.
2855: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
