func SysProcAttrSetsid ¶

func SysProcAttrSetsid(attr *syscall.SysProcAttr)

SysProcAttrSetsid run a program in a new session, is used to detach the process from the parent (normally a shell)

The disowning of a child process is accomplished by executing the system call setpgrp() or setsid(), (both of which have the same functionality) as soon as the child is forked. These calls create a new process session group, make the child process the session leader, and set the process group ID to the process ID of the child. https://bsdmag.org/unix-kernel-system-calls/
