15 pcap_set_tstamp_type() sets the type of time stamp desired for packets
16 captured on the pcap descriptor to the type specified by tstamp_type.
17 It must be called on a pcap descriptor created by pcap_create(3PCAP)
18 that has not yet been activated by pcap_activate(3PCAP).
19 pcap_list_tstamp_types(3PCAP) will give a list of the time stamp types
20 supported by a given capture device. See pcap-tstamp(7) for a list of
21 all the time stamp types.
22
24 pcap_set_tstamp_type() returns 0 on success if the specified time stamp
25 type is expected to be supported by the capture device, PCAP_WARN‐
26 ING_TSTAMP_TYPE_NOTSUP if the specified time stamp type is not sup‐
27 ported by the capture device, PCAP_ERROR_ACTIVATED if called on a cap‐
28 ture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE
29 if the capture device doesn't support setting the time stamp type (only
30 older versions of libpcap will return that; newer versions will always
31 allow the time stamp type to be set to the default type).
32
34 This function became available in libpcap release 1.2.1. In previous
35 releases, the time stamp type cannot be set; only the default time
36 stamp type offered by a capture source is available.
