1.17 cvs 2813: this function requests a resource designated by a URLname into a
2814: temporary filename. The download can come from a simple GET operation,
2815: or can come from POSTING/GETTING a form. In the latter

1.5 cvs 2818: 4 file retrieval modes are proposed:

2820: AMAYA_ISYNC : incremental, blocking mode
2821: AMAYA_ASYNC : non-blocking mode
2822: AMAYA_IASYNC : incremental, non-blocking mode
2823:
2824: In the incremental mode, each time a package arrives, it will be
2825: stored in the temporary file. In addition, if an
2826: incremental_callback function is defined, this function will be
2827: called and handled a copy of the newly received data package.
2828: Finally, if a terminate_callback function is defined, it will be
2829: invoked when the request terminates. The caller of this function
1.4 cvs 2830: can define two different contexts to be passed to the callback
2831: functions.
2832:
2833: When the function is called with the SYNC mode, the function will
2834: return only when the requested file has been loaded.
2835: The ASYNC mode will immediately return after setting up the
2836: call.
2837:
2838: Notes:
2839: At the end of a succesful request, the urlName string contains the
2840: name of the actually retrieved URL. As a URL can change over the time,
2841: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2842: caller verify the value of the urlName variable at the end of
1.4 cvs 2843: a request.
2844:
2845: Inputs:
2846: - docid Document identifier for the set of objects being
2847: retrieved.
2848: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2849: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
2850: - mode The retrieval mode.
