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);
DESCRIPTIONpcap_set_tstamp_precision() sets the precision of the time stamp
desired for packets captured on the pcap descriptor to the type speci‐
fied by tstamp_precision. It must be called on a pcap descriptor cre‐
ated by pcap_create() that has not yet been activated by pcap_acti‐
vate(). 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 VALUEpcap_set_tstamp_type() 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.
