推荐答案

在重叠的操作中:

呼叫 WSASend [

In a overlapped operation:

Call WSASend[^] with lpBuffers point to the file you want to download, for example:

WSABUF sendBuf;
sendBuf.buf = "GET /index.html HTTP/1.1\r\n\r\n";
sendBuf.len = strlen( sendBuf.buf );

WSASend( sock, &sendBuf, 1, &dwBytes, 0, &recvOv, SendComplete );

并在lpCompletionRoutine回调中处理缓冲区
WSARecv [

And process the buffer in your lpCompletionRoutine callback
WSARecv[^]

您好，Gokulnath，

根据您的评论，一种方法是
1)读取您在缓冲区中下载的文件，然后删除它.
和
2)我对此不确定，但是我找到了一个API

InternetReadFile -> [示例-> [ ^ ]

Hi Gokulnath,

As per your comments one way is
1) Read the file that you download in a buffer and than delete it.
and
2) I am not sure about this but I found one API

InternetReadFile ->[^]

Example ->[^]
