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.
