pcap_list_datalinks, pcap_free_datalinks - get a list of link-layer header types supported by a capture device, and free that list
SYNOPSIS
#include <pcap/pcap.h>
int pcap_list_datalinks(pcap_t *p, int **dlt_buf);
void pcap_free_datalinks(int *dlt_list);
DESCRIPTION
pcap_list_datalinks() is used to get a list of the supported link-layer header types of the interface associated with the pcap descriptor.
pcap_list_datalinks() allocates an array to hold the list and sets *dlt_buf to point to that array.
The caller is responsible for freeing the array with pcap_free_datalinks(), which frees the list of link-layer header types pointed to by
dlt_list.
RETURN VALUE
pcap_list_datalinks() returns the number of link-layer header types in the array on success and -1 on failure. If -1 is returned,
pcap_geterr() or pcap_perror() may be called with p as an argument to fetch or display the error text.
