.SH NAME
|
|
pcap_stats \- get capture statistics
|
|
.SH SYNOPSIS
|
|
.nf

.ft B
|
|
#include <pcap/pcap.h>
|
|
.ft
|
|

|
.SH DESCRIPTION
|
|
.B pcap_stats()
|
|
fills in the
|
|
.I 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.
|
|
.PP
|
|
.B 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''.
|
|
.SH RETURN VALUE
|
|
.B pcap_stats()
|
|
returns 0 on success and returns \-1 if there is an error or the
|
|
.I p
|
|
doesn't support packet statistics.
|
|
If \-1 is returned,
|
|
.B pcap_geterr()
|
|
or
|
|
.B pcap_perror()
|
|
may be called with
|
|
.I p
|
|
as an argument to fetch or display the error text.
