2736:
2737: In the incremental mode, each time a package arrives, it will be

2740: called and handled a copy of the newly received data package.

2745:

2748: The ASYNC mode will immediately return after setting up the

2751: Notes:
2752: At the end of a succesful request, the urlName string contains the
2753: name of the actually retrieved URL. As a URL can change over the time,
2754: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2755: caller verify the value of the urlName variable at the end of
1.4 cvs 2756: a request.
2757:
2758: Inputs:
2759: - docid Document identifier for the set of objects being
2760: retrieved.
2761: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2762: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
