Hi, thank you for your answer,

can't I kill the system call process by pid and call it using fork ? By doing additional research I understood that my first code was poorly designed and that I should use a separate thread, could you provide me an example doing a separate thread and then killing it by using a clean way like Signals or PID please ?
