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.
