The man page for the current version of libpcap does a better job of
documenting that than the libpcap 0.4 man page text I cited:
pcap_compile() is used to compile the string str into a
filter program. program is a pointer to a bpf_program
struct and is filled in by pcap_compile(). optimize con-
trols whether optimization on the resulting code is per-
formed. netmask specifies the netmask of the local net.
A return of -1 indicates an error in which case
pcap_geterr() may be used to display the error text.
