1969: AMAYA_ISYNC : incremental, blocking mode
1970: AMAYA_ASYNC : non-blocking mode
1971: AMAYA_IASYNC : incremental, non-blocking mode
1972:
1973: In the incremental mode, each time a package arrives, it will be
1974: stored in the temporary file. In addition, if an
1975: incremental_callback function is defined, this function will be
1976: called and handled a copy of the newly received data package.
1977: Finally, if a terminate_callback function is defined, it will be
1978: invoked when the request terminates. The caller of this function
1.4 cvs 1979: can define two different contexts to be passed to the callback
1980: functions.
1981:
1982: When the function is called with the SYNC mode, the function will
1983: return only when the requested file has been loaded.
1984: The ASYNC mode will immediately return after setting up the
1985: call.

1987: Notes:
1988: At the end of a succesful request, the urlName string contains the
1989: name of the actually retrieved URL. As a URL can change over the time,
1990: (e.g., be redirected elsewhere), it is advised that the function
1.17 cvs 1991: caller verify the value of the urlName variable at the end of
1.4 cvs 1992: a request.
1993:
1994: Inputs:
1995: - docid Document identifier for the set of objects being
1996: retrieved.
1997: - urlName The URL to be retrieved (MAX_URL_LENGTH chars length)
1998: - outputfile A pointer to an empty string of MAX_URL_LENGTH.
1999: - mode The retrieval mode.

2002: Callback and context for the incremental modes
2003: - terminate_cbf
2004: - context_icbf

1.17 cvs 2006: -error_html if TRUE, then display any server error message as an
2007: HTML document.
1.88 cvs 2008: - content_type a string
2009:
1.4 cvs 2010: Outputs:
2011: - urlName The URL that was retrieved
2012: - outputfile The name of the temporary file which holds the
2013: retrieved data. (Only in case of success)
1.88 cvs 2014: - if content_type wasn't NULL, it will contain a copy of the parameter
2015: sent in the HTTP answer
