在使用可提醒I/O时,系统为程序发起I/O的线程创建了一个APC(Async Procedure Call)队列,在设备完成I/O操作时,驱动程序将操作结果放入该队列,其中包含程序传递给系统的完成回调函数和重叠结构,对程序来说,该队列是透明的。此时线程还不知道是否IO完成。在线程进入可提醒状态(调用了SleepEx及Wait*等函数),系统遍历队...
然后将它们分配给lEvent就可以了,例如: WSAAsyncSeltct(s, hwnd,WM_SOCKET, FD_CONNECT | FD_READ | FD_WRITE | FD_CLOSE); 解释说明:我们的应用程序以后便可在套接字s上,接收到有关连接、发送、接收以及套接字关闭这一系列网络事件的通知。 FD_READ 应用程序想要接收有关是否可读的通知,以便读入数据 FD_...
According to the .NET documentation, async IO commands can be used to execute File operations in parallel: https://learn.microsoft.com/en-us/dotnet/csharp/asynchronous-programming/using-async-for-file-access#parallel-asynchronous-ioHowever, a small modification of the above shows that this is not...
异步,无缓冲的I / O:asynchio /f*.dat / n 操作已按请求顺序完成。 500个请求在0.224264秒内排队。 500个请求在4.982481秒内完成。 此测试表明前面提到的程序很快发出了500个I / O请求,并且有很多时间做其他工作或发出更多请求。 测试2 同步,无缓冲I / O:asynchio /f*.dat / s / n 按发出...
Description Calls to both new System.IO.FilesStream(... async: true) and Systeml.IO.ReadAllBytesAsync() both execute synchronously on windows. On Linux they work as expected. This behaviour was replicated on .NET 6, .NET 8 and .NET Frame...
