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.
