   pcap_set_tstamp_type.3pcap    ( 3 )

---

---

Имя (Name)

pcap_set_tstamp_type - set the time stamp type to be used by a capture device

---

Синопсис (Synopsis)

#include <pcap/pcap.h>

int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);

---

Описание (Description)

pcap_set_tstamp_type() sets the type of time stamp desired for packets captured on the pcap descriptor to the type specified by tstamp_type. It must be called on a pcap descriptor created by pcap_create(3PCAP) that has not yet been activated by pcap_activate(3PCAP). pcap_list_tstamp_types(3PCAP) will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of all the time stamp types.

---

Возвращаемое значение (Return value)

pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARNING_TSTAMP_TYPE_NOTSUP if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time stamp type (only older versions of libpcap will return that; newer versions will always allow the time stamp type to be set to the default type).

---

Обратная совместимость (Backward compatibility)

This function became available in libpcap release 1.2.1. In previous releases, the time stamp type cannot be set; only the default time stamp type offered by a capture source is available.
