Daemon and joindaemon DaemonI. Preface A program has at least one main thread. After the main thread is started, there is no affiliation between them. The main thread and subthread are executed in parallel and independent from each other. After the execution of the main thread is completed, it will not wait until the execution of the sub-thread ends. If there are other programs, it will run another program. If not, it will wait until the sub-thread fi

What is the difference between a daemon thread and a normal thread, the method Setdaemon (true) that invokes the thread object before the thread is started can be set as a daemon thread.Daemon threads use less, but are not useless, for example, the JVM's garbage collection, memory management, and other threads are daemon threads. There is in the database applicat

The general server program is running in the background process (daemon), so how to make the server process daemon?Here are the steps you follow to write the daemon:1. Create a child process, close the parent process, 2. Sets the file permission mask. When a process creates a new file (using the open (const char *pathname, int flags, mode_t mode) system call, the

In this case, if the main thread executes, the thread exits regardless of whether the child thread is complete or not. Here the basic and join () methods are reversed. In addition, there is a special note that must be set before the start () method call, and if not
