SYNOPSIS

       #include <pcap/pcap.h>

       int pcap_snapshot(pcap_t *p);


DESCRIPTION

       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_ERROR_NOT_ACTIVATED  if  called  on a capture handle that has been
       created but not activated.
