InternetReadFileEx(
    IN HINTERNET hFile,
    OUT LPINTERNET_BUFFERS lpBuffersOut,
    IN DWORD dwFlags,
    IN DWORD dwContext
);
Reads data from a handle opened by the InternetOpenUrl, FtpOpenFile, GopherOpenFile, or HttpOpenRequest function.
Returns TRUE if successful, or FALSE otherwise. To get extended error information, call GetLastError. An application can also use InternetGetLastResponseInfo when necessary.

HINTERNET handle returned by the InternetOpenUrl, FtpOpenFile, GopherOpenFile, or HttpOpenRequest function.
lpBuffersOut
Address of an INTERNET_BUFFERS structure that contains the data downloaded.
dwFlags
DWORD variable that contains the flags controlling the download. Can be one of the following values:

IRF_ASYNC Identical to WININET_API_FLAG_ASYNC.

IRF_SYNC Identical to WININET_API_FLAG_SYNC.

IRF_USE_CONTEXT Identical to WININET_API_FLAG_USE_CONTEXT.

IRF_NO_WAIT Do not wait for data. If there is data available, the function returns either the amount of data requested or the amount of data available (whichever is smaller).
