PCAP_SET_TSTAMP_PRECISION(3Library Functions ManuaPCAP_SET_TSTAMP_PRECISION(3)

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  de-
       sired 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(3)  that  has  not  yet been	activated by pcap_activate(3).
       Two time	stamp precisions are supported,	microseconds and  nanoseconds.
       One  can	use options PCAP_TSTAMP_PRECISION_MICRO	and PCAP_TSTAMP_PRECI-
       SION_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 sup-
       port 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.
