SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_snapshot(pcap_t *p);


DESCRIPTION

       pcap_snapshot()    returns   the   snapshot   length   specified   when
       pcap_set_snaplen(3) or pcap_open_live(3) was called, for  a  live  cap-
       ture, or the snapshot length from the capture file, for a ``savefile''.

       It must not be called on a pcap descriptor  created  by  pcap_create(3)
       that has not yet been activated by pcap_activate(3).

       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.
