NAME         top

       pcap_set_tstamp_precision  - set the time stamp precision returned in
       captures

SYNOPSIS         top

       #include <pcap/pcap.h>

       int pcap_set_tstamp_precision(pcap_t *p, int tstamp_precision);

DESCRIPTION         top

       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         top

       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.
