Java.nio.channels.AsynchronousChannel provides an asynchronous write file method,The specific code is as follows: Public Static voidsyncwrite (String path) {File file=NewFile (path+ "Warn.log"); if(!file.exists ()) {File.createnewfile (); } Path Pathsyn= Paths.get (path+line+ "Warn.log"); Try{Asynchronousfilechannel Channel=Asynchronousfilechannel.open

1. Idea: In order to achieve a variety of file size can be sent and received, can set the buffer loop send and receive, and record the location of the file read, if the number of bytes read into the buffer is less than the size of the buffer, then the file is sent, exit the Send loop, close the connection. And the CSocket is blocked, the receiving end can receive

Because the Second Life is a 3D display software, it needs to constantly download a large amount of data from the server, such as texture images, different roles use different texture images for different clothing appearances. When these roles are displayed, the texture image downloaded from the server is used. If many characters are displayed, such as 30, these texture images need to be saved to the disk. So how to save it to the disk? A good file sy

Because Second Life is a 3D display software, it needs to constantly download a large amount of data from the server, such as texture pictures, different characters are using different texture pictures to achieve different clothing appearance. When these roles are displayed, the texture pictures downloaded from the server are used. If you show more personas, such as 30 people, these textures will need to be saved to disk. So how to save it to disk. Saving to disk requires a good

This article describes an example of a multi-threaded file server. The server sends the required files to the client based on the client's request. multithreading is used to provide services for multiple clients at the same time. such requirements exist in many practical applications. The entire server program consists of four files: fileserver. c, fileclient. c, rw. h and rw. c. fileserver. c is the main program of the multi-

When multiple control threads share the same memory, you need to ensure that each thread sees a consistent view of the data.If the variables used by each thread are not read and modified by other threads, then there is no problem of consistency.The thread mutex is used to protect data and to ensure that only one thread

An exception occurs when multiple threads are simultaneously written in sqlite programming. I wrote a class to solve this problem. The idea is simple, that is, when a write operation is started, write down the id of the managed thread for the write operation, indicating that there are threads currently performing the write operation; when other threads write, you need to first check whether a process is performing write operations. If yes, you need to
