use something like:

myprog > /dev/null 2>&1

The last bit makes the stderr file descriptor point at the same place
as stdout.

try:

system("myprog > /dev/null 2>&1")

BTW I hope you understand that system is rather a dangerous call to
use in some situations (notably setuid binaries =:-O) because it just
execs /bin/sh to run the command you give it and hence is open to all
sorts of nasty hacker type attacks.  A whole load of these bugs were
cleaned out of Linux earlier this year.
