Hi all,

I would like to create independent process (I mean PPID to 1) using fork and exec.

I will run sub command from main and would like to keep the sub command as independent of the main.

I had tried setsid , but no help !!!

Thanks.
-------------------------------------------------
* using setsid() : setsid creates a session to the process. But still the parent process will ( PPID ) be the main process. IF we give the TERM signal to the sub process it creates zombiee process if the main process is active.

* We can use SIG{CHLD} ignore or TERM ..but in linux its throwing some debug message in /var/log/messages. So , we need to use waitpid(). BUt I Don't want to work on that. I just want to run another command independent of the main ( ie .making init process as parent ).
