1.15 cvs 1970: GetObjectWWW
1.17 cvs 1971: this function requests a resource designated by a URLname into a
1972: temporary filename. The download can come from a simple GET operation,
1973: or can come from POSTING/GETTING a form. In the latter
1974: case, the function receives a query string to send to the server.
1975:
1.5 cvs 1976: 4 file retrieval modes are proposed:
1977: AMAYA_SYNC : blocking mode
1978: AMAYA_ISYNC : incremental, blocking mode
1979: AMAYA_ASYNC : non-blocking mode
1980: AMAYA_IASYNC : incremental, non-blocking mode
1981:
1982: In the incremental mode, each time a package arrives, it will be
1983: stored in the temporary file. In addition, if an
1984: incremental_callback function is defined, this function will be
1985: called and handled a copy of the newly received data package.
1986: Finally, if a terminate_callback function is defined, it will be
1987: invoked when the request terminates. The caller of this function
1.4 cvs 1988: can define two different contexts to be passed to the callback
1989: functions.
1990:
1991: When the function is called with the SYNC mode, the function will
1992: return only when the requested file has been loaded.
1993: The ASYNC mode will immediately return after setting up the
1994: call.
1995:
1996: Notes:
1997: At the end of a succesful request, the urlName string contains the
1998: name of the actually retrieved URL. As a URL can change over the time,
1999: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 2000: caller verify the value of the urlName variable at the end of
1.4 cvs 2001: a request.
2002:
2003: Inputs:
2004: - docid Document identifier for the set of objects being
2005: retrieved.
2006: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2007: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
2008: - mode The retrieval mode.
2009: - incremental_cbf
2010: - context_icbf
2011: Callback and context for the incremental modes
2012: - terminate_cbf
2013: - context_icbf
2014: Callback and context for a terminate handler
1.17 cvs 2015: -error_html if TRUE, then display any server error message as an
2016: HTML document.
1.88 cvs 2017: - content_type a string
2018:
1.4 cvs 2019: Outputs:
2020: - urlName The URL that was retrieved
2021: - outputfile The name of the temporary file which holds the
2022: retrieved data. (Only in case of success)
1.88 cvs 2023: - if content_type wasn't NULL, it will contain a copy of the parameter
2024: sent in the HTTP answer
