Description
pcap_geterr() returns the error text pertaining to the last pcap library error. NOTE: the pointer it
returns will no longer point to a valid error message string after the pcap_t passed to it is closed; you
must use or copy the string before closing the pcap_t.
pcap_perror() prints the text of the last pcap library error on stderr, prefixed by prefix.
