I am learning how to program in Linux OS platform and what is the implementation to run my app in background process.

Like for example in this scenario: When executing my app in the shell it will automatically run in background process. Take note that I don’t need the “&” in the shell when I run my app. What standard Linux function to do this implementation?

And how can I kill or terminate the app that was run in background in the code? What I mean is I don’t need to execute the kill shell command to terminate my app in background? Or if the app meets a condition then it will kill itself or terminate itself.

Many thanks.

    You want to daemonize your program. This is generally done by fork() and a few other system calls.

    Background applications can be killed by using kill. It is good practice for a daemon to write its process ID (PID) in a well-known file so it can be located easily.
