PCAP_SET_TSTAMP_PRECISION(3PCAP) PCAP_SET_TSTAMP_PRECISION(3PCAP)
pcap_set_tstamp_precision - set the time stamp precision returned in
captures
#include <pcap/pcap.h>
int pcap_set_tstamp_precision(pcap_t *p, int tstamp_precision);
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.
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.
