1.17 cvs 2799: this function requests a resource designated by a URLname into a
2800: temporary filename. The download can come from a simple GET operation,

1.5 cvs 2804: 4 file retrieval modes are proposed:

2808: AMAYA_IASYNC : incremental, non-blocking mode
2809:
2810: In the incremental mode, each time a package arrives, it will be
2811: stored in the temporary file. In addition, if an
2812: incremental_callback function is defined, this function will be
2813: called and handled a copy of the newly received data package.
2814: Finally, if a terminate_callback function is defined, it will be
2815: invoked when the request terminates. The caller of this function
1.4 cvs 2816: can define two different contexts to be passed to the callback
2817: functions.
2818:
2819: When the function is called with the SYNC mode, the function will
2820: return only when the requested file has been loaded.
2821: The ASYNC mode will immediately return after setting up the
2822: call.
2823:
2824: Notes:
2825: At the end of a succesful request, the urlName string contains the
2826: name of the actually retrieved URL. As a URL can change over the time,
2827: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2828: caller verify the value of the urlName variable at the end of
1.4 cvs 2829: a request.

2831: Inputs:
2832: - docid Document identifier for the set of objects being
2833: retrieved.
2834: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)

2836: - mode The retrieval mode.
