2453:
2454: In the incremental mode, each time a package arrives, it will be

2456: incremental_callback function is defined, this function will be
2457: called and handled a copy of the newly received data package.

2462:
2463: When the function is called with the SYNC mode, the function will

2465: The ASYNC mode will immediately return after setting up the

2468: Notes:
2469: At the end of a succesful request, the urlName string contains the
2470: name of the actually retrieved URL. As a URL can change over the time,
2471: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2472: caller verify the value of the urlName variable at the end of
1.4 cvs 2473: a request.

2475: Inputs:
2476: - docid Document identifier for the set of objects being
2477: retrieved.
2478: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)

2771:

2780: At the end of a succesful request, the urlName string contains the

2782: (e.g., be redirected elsewhere), it is advised that the function
2783: caller verifies the value of the urlName variable at the end of

2785:
2786: Inputs:
2787: - docid Document identifier for the set of objects being
2788: retrieved.
2789: - fileName A pointer to the local file to upload
2790: - urlName The URL to be uploaded (MAX_URL_LENGTH chars length)
2791: - mode The retrieval mode.
2792: - terminate_cbf
2793: - context_icbf
2794: Callback and context for a terminate handler
