1.17 cvs 2784: this function requests a resource designated by a URLname into a
2785: temporary filename. The download can come from a simple GET operation,
2786: or can come from POSTING/GETTING a form. In the latter
2787: case, the function receives a query string to send to the server.
2788:
1.5 cvs 2789: 4 file retrieval modes are proposed:
2790: AMAYA_SYNC : blocking mode
2791: AMAYA_ISYNC : incremental, blocking mode
2792: AMAYA_ASYNC : non-blocking mode
2793: AMAYA_IASYNC : incremental, non-blocking mode
2794:
2795: In the incremental mode, each time a package arrives, it will be
2796: stored in the temporary file. In addition, if an
2797: incremental_callback function is defined, this function will be
2798: called and handled a copy of the newly received data package.
2799: Finally, if a terminate_callback function is defined, it will be
2800: invoked when the request terminates. The caller of this function
1.4 cvs 2801: can define two different contexts to be passed to the callback
2802: functions.
2803:
2804: When the function is called with the SYNC mode, the function will
2805: return only when the requested file has been loaded.
2806: The ASYNC mode will immediately return after setting up the
2807: call.
2808:
2809: Notes:
2810: At the end of a succesful request, the urlName string contains the
2811: name of the actually retrieved URL. As a URL can change over the time,
2812: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2813: caller verify the value of the urlName variable at the end of
1.4 cvs 2814: a request.
2815:
2816: Inputs:
2817: - docid Document identifier for the set of objects being
2818: retrieved.
2819: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2820: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
2821: - mode The retrieval mode.
