PCAP_SET_TSTAMP_PRECISION(3PCAP) PCAP_SET_TSTAMP_PRECISION(3PCAP)
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(3PCAP) that has not yet been
activated by pcap_activate(3PCAP). 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 capture
device, PCAP_ERROR_TSTAMP_PRECISION_NOTSUP if the capture device
does not support the requested time stamp precision,
PCAP_ERROR_ACTIVATED if called on a capture handle that has been
activated.
BACKWARD COMPATIBILITY
This function became available in libpcap release 1.5.1. In
previous releases, time stamps from a capture device or savefile
are always given in seconds and microseconds.
