<p class="level0"><a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0"><span Class="bold">pcap_set_tstamp_precision</span>() sets the precision of the time stamp desired for packets captured on the pcap descriptor to the type specified by <span Class="emphasis">tstamp_precision</span>. It must be called on a pcap descriptor created by <a Class="bold" href="./pcap_create.html">pcap_create</a>(3PCAP) that has not yet been activated by <a Class="bold" href="./pcap_activate.html">pcap_activate</a>(3PCAP). Two time stamp precisions are supported, microseconds and nanoseconds. One can use options <span Class="bold">PCAP_TSTAMP_PRECISION_MICRO and</span> <span Class="bold">PCAP_TSTAMP_PRECISION_NANO</span> to request desired precision. By default, time stamps are in microseconds. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0"><span Class="bold">pcap_set_tstamp_precision</span>() returns <span Class="bold">0</span> on success if the specified time stamp precision is expected to be supported by the capture device, <span Class="bold">PCAP_ERROR_TSTAMP_PRECISION_NOTSUP</span> if the capture device does not support the requested time stamp precision, <span Class="bold">PCAP_ERROR_ACTIVATED</span> if called on a capture handle that has been activated. <a name="BACKWARD"></a><h2 class="nroffsh">BACKWARD COMPATIBILITY</h2>
<p class="level0">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. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
