<p class="level0"><a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0"><span Class="bold">pcap_set_timeout</span>() sets the packet buffer timeout that will be used on a capture handle when the handle is activated to <span Class="emphasis">to_ms</span>, which is in units of milliseconds.  (See <a Class="bold" href="./pcap.html">pcap</a>(3PCAP) for an explanation of the packet buffer timeout.) 
<p class="level0">The behavior, if the timeout isn&#39;t specified, is undefined, as is the behavior if the timeout is set to zero or to a negative value.  We recommend always setting the timeout to a non-zero value unless immediate mode is set, in which case the timeout has no effect. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0"><span Class="bold">pcap_set_timeout</span>() returns <span Class="bold">0</span> on success or <span Class="bold">PCAP_ERROR_ACTIVATED</span> if called on a capture handle that has been activated. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
