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


#include <pcap/pcap.h>

int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);


pcap_set_tstamp_type() sets the 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() that has not yet been activated by pcap_activate(). pcap_list_tstamp_types() 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.

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.
