PCAP_SET_TSTAMP_TYPE(3PCAP)PCAP_SET_TSTAMP_TYPE(3PCAP)NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device
SYNOPSIS
#include <pcap/pcap.h>
int pcap_set_tstamp_type(pcap_t *p, int tstamp_type);
DESCRIPTION
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_WARN-
ING_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.
