NAME

       pcap_set_tstamp_precision  -  set  the time stamp precision returned in
       captures


SYNOPSIS

       #include <pcap/pcap.h>

       pcap_set_tstamp_precision(3) *p, int tstamp_precision);


DESCRIPTION

       pcap_set_tstamp_precision(3)  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_precision(3)  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.
