NAME
pcap_stats - get capture statistics
SYNOPSIS
#include <pcap/pcap.h>int pcap_stats(pcap_t *p, struct pcap_stat *ps);
DESCRIPTION
pcap_stats() fills in the
pcap_stat structure pointed to by its second argument. The values represent
packet statistics from the start of the run to the time of the call.
pcap_stats() is supported only on live captures, not on ``savefiles''; no statistics are stored in ``savefiles'', so no statistics are available when reading from a ``savefile''.
RETURN VALUE
pcap_stats() returns 0 on success and returns -1 if there is an error or the
p doesn't support packet statistics.
If -1 is returned,
pcap_geterr() or
pcap_perror() may be called with
p as an argument to fetch or display the error text.
