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_snapshot() or pcap_open_live() 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() that has not yet been activated by pcap_activate().

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.
