ENOTTY (errno 25) on system() call with a deamonize binary on SCO Unix 1

[desb0]

Hi,

I try to call in a c binary the following command.

system("pack_it");

where pack_it is a little binary that compress a file.

The trouble is that my binary that call system("pack_it"); is a deamonize binary. So no TTY associated with it.

So system("pack_it); return ENOTTY (errno 25).

So ... HOW THE HELL DO I CALL ANOTHER BINARY WITHIN A DEAMONIZE BINARY?

Thank you ^_^

Have you tried something like this ?
system("pack_it >&- 2>&- <&-");

Another way is to play with fork() and exec()

Hope This Helps, PH.
