NAME
       pcap_set_timeout - set the read timeout for a not-yet-activated capture handle

SYNOPSIS
       #include <pcap/pcap.h>

       int pcap_set_timeout(pcap_t *p, int to_ms);

DESCRIPTION
       pcap_set_timeout()  sets the read timeout that will be used on a capture handle when the handle is activated to to_ms, which is in units of
       milliseconds.

       The behavior, if the timeout isn't specified, is undefined.  We recommend always setting the timeout to a non-zero value  unless  immediate
       mode is set, in which case the timeout has no effect.

RETURN VALUE
       pcap_set_timeout() returns 0 on success or PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated.
