pcap_set_tstamp_precision - set the time stamp precision returned in
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 speci-
fied by tstamp_precision. It must be called on a pcap descriptor cre-
ated by pcap_create(3) that has not yet been activated by pcap_acti-
vate(3). 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 capture device,
PCAP_ERROR_TSTAMP_PRECISION_NOTSUP if the capture device does not sup-
port the requested time stamp precision, PCAP_ERROR_ACTIVATED if called
on a capture handle that has been activated.
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.
