/*
 * This header defines the few things we need to write files in the pcap
 * format. The identifiers are the same as in the system's pcap/pcap.h, but
 * the types have been standardized. Note that the timestamp parts have to be
 * put separately, since "struct timeval" may be padded.
 *
 * The reason for having our own header instead of just using pcap/pcap.h is
 * to avoid a build-dependency on libpcap.
