#include <pcap/pcap.h>
int pcap_get_tstamp_precision(pcap_t *p);


pcap_get_tstamp_precision() returns the precision of the time stamp returned in packet captures on the pcap descriptor.

Return value

pcap_get_tstamp_precision() returns PCAP_TSTAMP_PRECISION_MICRO or PCAP_TSTAMP_PRECISION_NANO, which indicates that pcap captures contains time stamps in microseconds or nanoseconds respectively.
