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.
