NAME
pcap_set_tstamp_precision - set the time stamp precision returned in
captures
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_tstamp_precision(pcap_t *p, int tstamp_precision);
DESCRIPTION
pcap_set_tstamp_precision()
sets the precision of the time stamp desired for packets captured on the pcap
descriptor to the type specified by
tstamp_precision.
It must be called on a pcap descriptor created by
pcap_create()
that has not yet been activated by
pcap_activate().
Two time stamp precisions are supported, microseconds and nanoseconds. One can
use options
PCAP_TSTAMP_PRECISION_MICRO and
PCAP_TSTAMP_PRECISION_NANO
to request desired precision. By default, time stamps are in microseconds.
RETURN VALUE
pcap_set_tstamp_precision()
returns 0 on success if the specified time stamp precision is expected to be
supported by the operating system,
PCAP_ERROR_TSTAMP_PRECISION_NOTSUP
if operating system does not support requested time stamp precision,
PCAP_ERROR_ACTIVATED
if called on a capture handle that has been activated.
