PCAP_LIST_TSTAMP_TYPES(3PCAP) PCAP_LIST_TSTAMP_TYPES(3PCAP)
pcap_list_tstamp_types, pcap_free_tstamp_types - get a list of
time stamp types supported by a capture device, and free that
list
#include <pcap/pcap.h>
int pcap_list_tstamp_types(pcap_t *p, int **tstamp_typesp);
void pcap_free_tstamp_types(int *tstamp_types);
pcap_list_tstamp_types() is used to get a list of the supported
time stamp types of the interface associated with the pcap
descriptor. pcap_list_tstamp_types() allocates an array to hold
the list and sets *tstamp_typesp to point to the array. See
pcap-tstamp(7) for a list of all the time stamp types.
The caller is responsible for freeing the array with
pcap_free_tstamp_types(), which frees the list pointed to by
tstamp_types.
pcap_list_tstamp_types() returns the number of time stamp types
in the array on success and PCAP_ERROR on failure. A return
value of one means that the only time stamp type supported is the
one in the list, which is the capture device's default time stamp
type. A return value of zero means that the only time stamp type
supported is PCAP_TSTAMP_HOST, which is the capture device's
default time stamp type (only older versions of libpcap will
return that; newer versions will always return one or more
types). If PCAP_ERROR is returned, pcap_geterr(3PCAP) or
pcap_perror(3PCAP) may be called with p as an argument to fetch
or display the error text.
These functions 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.
