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 specified by tstamp_precision. It must be called on a pcap descriptor created by pcap_create(3PCAP) that has not yet been activated by pcap_activate(3PCAP). 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 capture device, PCAP_ERROR_TSTAMP_PRECISION_NOTSUP if the capture device does not support the requested time stamp precision, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated.  

BACKWARD COMPATIBILITY

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.
