("of course"? Linux isn't the only OS with STDOUT, or libpcap.... :-))
What happens if your application tries to write to the standard output?
Tcpdump and Tethereal are two programs that use "pcap_setfilter()" when
capturing and that (if not run with the "-w" flag, which causes them to
save a binary capture file) send a dissected form of the packets to the
standard output as text, so "pcap_setfilter()", by itself, doesn't
prevent a program from writing to the standard output.
