IntroductionStrace is commonly used to track system calls and received signals when a process executes. In the Linux world, processes cannot directly access hardware devices, and when a process requires access to a hardware device (such as reading a

Orphan process and daemon processThrough the previous study we learned how to create a process through the fork () function and the vfork () function. Now let's go into two special processes: The orphan process and the daemon.I. The orphan process1.

Linux DaemonDaemon (Daemon) It is carried out in a specific process background.Event. Daemons are a very practical process. Most of Linux's servers are implemented with daemon processes. Example. INTERNETSERVERINETD,WEBSERVERHTTPD and so on. At the

For Java, typically one application has only one process--JVM. Unless a new process is derived or opened in the code.threads, of course, are opened by the process. When the process that opened the thread leaves, the thread is no longer there.So, for

When using Quick-cocos2d-x to do a project hot update, I need to create a temporary folder to save the downloaded update package. After the update is complete, I need to delete these temporary files and folders. Cocos2d-x and Quick-cocos2d-x do not

Create child process, parent process exitsThis is the first step in the process of writing a daemon. Since the daemon is detached from the control terminal, the first step is to create the illusion that a program has been completed in the shell

Sometimes, in order to migrate large amounts of data quickly, it is possible to temporarily mount NTFS-formatted mobile hard disks on Linux servers, in general, Linux can not recognize the NTFS-formatted mobile hard disk (need to recompile Linux

A daemon (Daemon) is a special process running in the background. It is independent of the control terminal and periodically performs a task or waits to handle certain occurrences. The daemon is a very useful process. PHP can also implement the
