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 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 VALUE
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.
