PCAP_LIST_TSTAMP_TYPES(3pcap)
NAME
pcap_list_tstamp_types, pcap_free_tstamp_types - get a list of time
stamp types supported by a capture device, and free that list
SYNOPSIS
#include <pcap/pcap.h>
int pcap_list_tstamp_types(pcap_t *p, int **tstamp_typesp);
void pcap_free_tstamp_types(int *tstamp_types);
DESCRIPTION
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.
RETURN VALUE
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.
BACKWARD COMPATIBILITY
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.
