NAME

pcap_datalink_val_to_name, pcap_datalink_val_to_description, pcap_datalink_val_to_description_or_dlt - get a name or description for a link-layer header type value

CONTENTS

SYNOPSIS

#include <pcap.h>


const char *pcap_datalink_val_to_name(int dlt);
const char *pcap_datalink_val_to_description(int dlt);
const char *pcap_datalink_val_to_description_or_dlt(int dlt);

DESCRIPTION

pcap_datalink_val_to_name() translates a link-layer header type value to the corresponding link-layer header type name, which is the DLT_ name for the link-layer header type value with the DLT_ removed. NULL is returned if the type value does not correspond to a known DLT_ value.

pcap_datalink_val_to_description() translates a link-layer header type value to a short description of that link-layer header type. NULL is returned if the type value does not correspond to a known DLT_ value.

pcap_datalink_val_to_description_or_dlt() translates a link-layer header type value to a short description of that link-layer header type just like pcap_datalink_val_to_description. If the type value does not correspond to a known DLT_ value, the string "DLT n" is returned, where n is the value of the dlt argument.

“ Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.” ”
