Defined There are two types of threads in Java: The user thread, and the Daemon thread. A daemon thread is a special kind of thread that has a special meaning of "companionship", which is automatically destroyed when a non-daemon thread does not exist in the thread. The garbage collection thread is a daemon thread, and

do this step). The parent process (session leader) exits and the child process resumes execution,//and no longer has the ability to open control terminals. After calling Init_daemon in the process being executed, the process becomes the daemon,//The out-of-control terminal executes in the background. if(Setsid () = =-1) {ngx_log_error (Ngx_log_emerg, log, Ngx_errno,"Setsid () failed"); returnNgx_error; } //Resetting document creation masks//i

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
