編集:問題は、コンテナー内の OVERLAPPED または WSAOVERLAPPED を完了ポートに関連付ける必要があることだと思います。あれは正しいですか?
誰かが私のサーバーに接続すると、IO 完了を取得できます。次に、新しいソケットで CreateIoCompletionPort を使用し、元のソケットが使用された完了ポートを使用します。しかし、彼らが私にデータを送信すると、それは開始されません。ただし、他の誰かが接続すると、それでも開始されます。私の質問は、なぜこれが起こるのでしょうか? また、CreateIoCompletionPort が元のハンドルと同じハンドルを返すようにします。何を与える?
