エヴェヨネ。
エラー コード 10054 を解決するにはどうすればよいですか? このエラーに関する記述があります。これが通信用の完全なソースコードです。私のコードが大丈夫かどうか知りたいです。
WSAECONNRESET10054 ピアによって接続がリセットされました。既存の接続がリモート ホストによって強制的に閉じられました。これは通常、リモート ホスト上のピア アプリケーションが突然停止した場合、ホストが再起動された場合、ホストまたはリモート ネットワーク インターフェイスが無効になった場合、またはリモート ホストがハード クローズを使用した場合に発生します (リモート ホストの SO_LINGER オプションの詳細については、setsockopt を参照してください)。ソケット）。このエラーは、1 つ以上の操作の進行中にキープアライブ アクティビティが障害を検出したために接続が切断された場合にも発生する可能性があります。進行中の操作は、WSAENETRESET で失敗します。以降の操作は、WSAECONNRESET で失敗します。
