pcap_set_tstamp_precision

PCAP_SET_TSTAMP_PRECISION(3)				     Library Functions Manual				      PCAP_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 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_PRE-
       CISION_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.
