PCAP_SNAPSHOT(3PCAP) PCAP_SNAPSHOT(3PCAP)
pcap_snapshot - get the snapshot length
#include <pcap/pcap.h>
int pcap_snapshot(pcap_t *p);
pcap_snapshot() returns the snapshot length specified when
pcap_set_snaplen(3PCAP) or pcap_open_live(3PCAP) was called, for a
live capture, or the snapshot length from the capture file, for a
``savefile''.
It must not be called on a pcap descriptor created by
pcap_create(3PCAP) that has not yet been activated by
pcap_activate(3PCAP).
pcap_snapshot() returns the snapshot length on success and
PCAP_ERROR_NOT_ACTIVATED if called on a capture handle that has
been created but not activated.
