PCAP_SET_TSTAMP_PRECISION(3)                          Library Functions Manual



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() 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.

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.
