pcap_setfilter() is used to specify a filter program. fp is a
pointer to a bpf_program struct, usually the result of a call to
pcap_compile(3PCAP).
ЗНАЧЕНИЕ ВОЗВРАТА
pcap_setfilter() returns 0 on success, PCAP_ERROR_NOT_ACTIVATED
if called on a capture handle that has been created but not
activated, or PCAP_ERROR on other errors. If PCAP_ERROR is
returned, pcap_geterr(3PCAP) or pcap_perror(3PCAP) may be called
with p as an argument to fetch or display the error text.
