pcap_geterr(3PCAP)
or
pcap_perror(3PCAP)
may be called with
p

Additional error codes may be added in the future; a program should
check for
0,
1,
and negative, return codes, and treat all negative
return codes as errors.
pcap_statustostr(3PCAP)
can be called, with a warning or error code as an argument, to fetch a
message describing the warning or error code.
