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 zero
means that you cannot specify a time stamp type; you are limited to the
capture device's default time stamp type. If
PCAP_ERROR is returned,
pcap_geterr() or
pcap_perror() may be called with
p as an
argument to fetch or display the error text.
