system() doesnt give me the control back ..

[Vaddina Prakash Rao]

Hello every one,
In our Linux Encoding system, a copy of helix dna producer is running
.....
i wrote an applicatoin which can remotely communicate with the
encoding machine ... Its function include

1. Kill currently running copy of the producer and
2. Restart the producer with new settings.

killing part of the producer was quite easy. But restarting it is
where i face problems. I use the system() function to issue the
command. But the problem is helix producer doesnt give back the
control to my program which makes my program not to respond. Does any
one have an idea for this ?? And can anyone suggest where does
function like fork, exec fit in my program ...

thanking you,
Vaddina Prakash Rao

You seek comp.unix.programmer since C does not specify how the program
invoked via system() must behave.

If you were "restarting" this program by-hand, by logging in to
this machine and typing a command, what would you type?

BTW, please read the FAQ for this group.

I use the same string as my command to restart the applicatoin which i
pass to the system() function. And it gives back the control to the
shell !!

Sorry !! I guess, I am in the wrong group ??
