1.15 cvs 1969: GetObjectWWW
1.17 cvs 1970: this function requests a resource designated by a URLname into a
1971: temporary filename. The download can come from a simple GET operation,
1972: or can come from POSTING/GETTING a form. In the latter
1973: case, the function receives a query string to send to the server.
1974:
1.5 cvs 1975: 4 file retrieval modes are proposed:
1976: AMAYA_SYNC : blocking mode
1977: AMAYA_ISYNC : incremental, blocking mode
1978: AMAYA_ASYNC : non-blocking mode
1979: AMAYA_IASYNC : incremental, non-blocking mode
1980:
1981: In the incremental mode, each time a package arrives, it will be
1982: stored in the temporary file. In addition, if an
1983: incremental_callback function is defined, this function will be
1984: called and handled a copy of the newly received data package.
1985: Finally, if a terminate_callback function is defined, it will be
1986: invoked when the request terminates. The caller of this function
1.4 cvs 1987: can define two different contexts to be passed to the callback
1988: functions.
1989:
1990: When the function is called with the SYNC mode, the function will
1991: return only when the requested file has been loaded.
1992: The ASYNC mode will immediately return after setting up the
1993: call.
1994:
1995: Notes:
1996: At the end of a succesful request, the urlName string contains the
1997: name of the actually retrieved URL. As a URL can change over the time,
1998: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 1999: caller verify the value of the urlName variable at the end of
1.4 cvs 2000: a request.
2001:
2002: Inputs:
2003: - docid Document identifier for the set of objects being
2004: retrieved.
2005: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
2006: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
2007: - mode The retrieval mode.
2008: - incremental_cbf
2009: - context_icbf
2010: Callback and context for the incremental modes
2011: - terminate_cbf
2012: - context_icbf
2013: Callback and context for a terminate handler
1.17 cvs 2014: -error_html if TRUE, then display any server error message as an
2015: HTML document.
1.88 cvs 2016: - content_type a string
2017:
1.4 cvs 2018: Outputs:
2019: - urlName The URL that was retrieved
2020: - outputfile The name of the temporary file which holds the
2021: retrieved data. (Only in case of success)
1.88 cvs 2022: - if content_type wasn't NULL, it will contain a copy of the parameter
2023: sent in the HTTP answer
