26 /* Flags are needed for, among other things, return HRESULTs from the Read function
27 * to conform to native. For example, Read returns:
29 * 1. E_PENDING if called before the request has completed,
31 * 2. S_FALSE after all data has been read and S_OK has been reported,
32 * (flags = FLAG_REQUEST_COMPLETE | FLAG_ALL_DATA_READ | FLAG_RESULT_REPORTED)
33 * 3. INET_E_DATA_NOT_AVAILABLE if InternetQueryDataAvailable fails. The first time
34 * this occurs, INET_E_DATA_NOT_AVAILABLE will also be reported to the sink,
35 * (flags = FLAG_REQUEST_COMPLETE)
36 * but upon subsequent calls to Read no reporting will take place, yet
37 * InternetQueryDataAvailable will still be called, and, on failure,
38 * INET_E_DATA_NOT_AVAILABLE will still be returned.
39 * (flags = FLAG_REQUEST_COMPLETE | FLAG_RESULT_REPORTED)
41 * FLAG_FIRST_DATA_REPORTED and FLAG_LAST_DATA_REPORTED are needed for proper
42 * ReportData reporting. For example, if OnResponse returns S_OK, Continue will
43 * report BSCF_FIRSTDATANOTIFICATION, and when all data has been read Read will
44 * report BSCF_INTERMEDIATEDATANOTIFICATION|BSCF_LASTDATANOTIFICATION. However,
45 * if OnResponse does not return S_OK, Continue will not report data, and Read
46 * will report BSCF_FIRSTDATANOTIFICATION|BSCF_LASTDATANOTIFICATION when all
