1.15 cvs 2769: GetObjectWWW
1.17 cvs 2770: this function requests a resource designated by a URLname into a
2771: temporary filename. The download can come from a simple GET operation,
2772: or can come from POSTING/GETTING a form. In the latter
2773: case, the function receives a query string to send to the server.
2774:
1.5 cvs 2775: 4 file retrieval modes are proposed:
2776: AMAYA_SYNC : blocking mode
2777: AMAYA_ISYNC : incremental, blocking mode
2778: AMAYA_ASYNC : non-blocking mode
2779: AMAYA_IASYNC : incremental, non-blocking mode
2780:
2781: In the incremental mode, each time a package arrives, it will be
2782: stored in the temporary file. In addition, if an
2783: incremental_callback function is defined, this function will be
2784: called and handled a copy of the newly received data package.
2785: Finally, if a terminate_callback function is defined, it will be
2786: invoked when the request terminates. The caller of this function
1.4 cvs 2787: can define two different contexts to be passed to the callback
2788: functions.
2789:
2790: When the function is called with the SYNC mode, the function will
2791: return only when the requested file has been loaded.
2792: The ASYNC mode will immediately return after setting up the
2793: call.
2794:
2795: Notes:
2796: At the end of a succesful request, the urlName string contains the
2797: name of the actually retrieved URL. As a URL can change over the time,
2798: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2799: caller verify the value of the urlName variable at the end of
1.4 cvs 2800: a request.
2801:
2802: Inputs:
2803: - docid Document identifier for the set of objects being
2804: retrieved.
2805: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2806: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
2807: - mode The retrieval mode.
2808: - incremental_cbf
2809: - context_icbf
2810: Callback and context for the incremental modes
2811: - terminate_cbf
2812: - context_icbf
2813: Callback and context for a terminate handler
1.17 cvs 2814: -error_html if TRUE, then display any server error message as an
2815: HTML document.
1.88 cvs 2816: - content_type a string
2817:
1.4 cvs 2818: Outputs:
2819: - urlName The URL that was retrieved
2820: - outputfile The name of the temporary file which holds the
2821: retrieved data. (Only in case of success)
1.88 cvs 2822: - if content_type wasn't NULL, it will contain a copy of the parameter
2823: sent in the HTTP answer

1.17 cvs 3172: PutObjectWWW
3173: frontend for uploading a resource to a URL. This function downloads
3174: a file to be uploaded into memory, it then calls UploadMemWWW to
3175: finish the job.
3176:
1.5 cvs 3177: 2 upload modes are proposed:
3178: AMAYA_SYNC : blocking mode
3179: AMAYA_ASYNC : non-blocking mode
3180:
1.4 cvs 3181: When the function is called with the SYNC mode, the function will
3182: return only when the file has been uploaded.
3183: The ASYNC mode will immediately return after setting up the
3184: call. Furthermore, at the end of an upload, the ASYNC mode will
3185: call back terminate_cbf, handling it the context defined in
3186: context_tcbf.
3187:
3188: Notes:
3189: At the end of a succesful request, the urlName string contains the
3190: name of the actually uploaded URL. As a URL can change over the time,
3191: (e.g., be redirected elsewhere), it is advised that the function
3192: caller verifies the value of the urlName variable at the end of
3193: a request.
3194:
3195: Inputs:
3196: - docid Document identifier for the set of objects being
3197: retrieved.
3198: - fileName A pointer to the local file to upload
3199: - urlName The URL to be uploaded (MAX_URL_LENGTH chars length)
3200: - mode The retrieval mode.
3201: - terminate_cbf
3202: - context_icbf
3203: Callback and context for a terminate handler
3204:
3205: Outputs:
3206: - urlName The URL that was uploaded
3207:
3208: Returns:
3209: HT_ERROR
3210: HT_OK
