PCAP_SET_TSTAMP_PRECISION(3PCAP)	      PCAP_SET_TSTAMP_PRECISION(3PCAP)

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_type() 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.
