1223: AMAYA_ISYNC : incremental, blocking mode
1224: AMAYA_ASYNC : non-blocking mode
1225: AMAYA_IASYNC : incremental, non-blocking mode
1226:
1227: In the incremental mode, each time a package arrives, it will be
1228: stored in the temporary file. In addition, if an
1229: incremental_callback function is defined, this function will be
1230: called and handled a copy of the newly received data package.
1231: Finally, if a terminate_callback function is defined, it will be
1232: invoked when the request terminates. The caller of this function
1.4 cvs 1233: can define two different contexts to be passed to the callback
1234: functions.
1235:
1236: When the function is called with the SYNC mode, the function will
1237: return only when the requested file has been loaded.
1238: The ASYNC mode will immediately return after setting up the
1239: call.
1240:
1241: Notes:
1242: At the end of a succesful request, the urlName string contains the
1243: name of the actually retrieved URL. As a URL can change over the time,
1244: (e.g., be redirected elsewhere), it is advised that the function
1245: caller verifies the value of the urlName variable at the end of
1246: a request.
1247:
1248: Inputs:
1249: - docid Document identifier for the set of objects being
1250: retrieved.
1251: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
1252: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
1253: - mode The retrieval mode.
1254: - incremental_cbf
1255: - context_icbf

1257: - terminate_cbf
1258: - context_icbf

1577:
1578: 2 upload modes are proposed:
1579: AMAYA_SYNC : blocking mode
1580: AMAYA_ASYNC : non-blocking mode
1581:
1582:
1.4 cvs 1583: When the function is called with the SYNC mode, the function will
1584: return only when the file has been uploaded.
1585: The ASYNC mode will immediately return after setting up the
1586: call. Furthermore, at the end of an upload, the ASYNC mode will
1587: call back terminate_cbf, handling it the context defined in
1588: context_tcbf.
1589:
1590: Notes:
1591: At the end of a succesful request, the urlName string contains the
1592: name of the actually uploaded URL. As a URL can change over the time,
1593: (e.g., be redirected elsewhere), it is advised that the function
1594: caller verifies the value of the urlName variable at the end of
1595: a request.
1596:
1597: Inputs:
1598: - docid Document identifier for the set of objects being
1599: retrieved.
1600: - fileName A pointer to the local file to upload
1601: - urlName The URL to be uploaded (MAX_URL_LENGTH chars length)
1602: - mode The retrieval mode.
1603:
1604: - terminate_cbf
1605: - context_icbf
1606: Callback and context for a terminate handler
1607:
1608: Outputs:
1609: - urlName The URL that was uploaded
1610:
1611: Returns:
1612: HT_ERROR
1613: HT_OK
