15 pcap_set_timeout() sets the packet buffer timeout that will be used on
16 a capture handle when the handle is activated to to_ms, which is in
17 units of milliseconds. (See pcap(3PCAP) for an explanation of the
18 packet buffer timeout.)
19
20 The behavior, if the timeout isn't specified, is undefined, as is the
21 behavior if the timeout is set to zero or to a negative value. We rec‐
22 ommend always setting the timeout to a non-zero value unless immediate
23 mode is set, in which case the timeout has no effect.
24
26 pcap_set_timeout() returns 0 on success or PCAP_ERROR_ACTIVATED if
27 called on a capture handle that has been activated.
