pcap_datalink_name_to_val - get the link-layer header type value corresponding to a header type name

#include <pcap/pcap.h>

int pcap_datalink_name_to_val(const char *name);

pcap_datalink_name_to_val() translates a link-layer header type name, which is a DLT_ name with the DLT_ removed, to the corresponding link-layer header type value. The translation is case-insensitive. pcap_datalink_name_to_val() returns the type value on success and -1 if the name is not a known type name.. pcap(3PCAP)
