Re: How to execute a process in background by exec functions?

["Wen Guangcheng" <wen.guangcheng@cnt.sp.qnes.nec.co.jp>]

Hi,
Thanks a lot for your help.
Yes, I have tired this way. The daemon started, but I hope its PPID
is 1. We can do it by calling system("/home/wen/daemon &").
How can I do it by fork&exec way?

Best regards,

--Wen
