pcap_set_datalink - set the link-layer header type to be used by
a capture device
#include <pcap/pcap.h>
int pcap_set_datalink(pcap_t *p, int dlt);
pcap_set_datalink() is used to set the current link-layer header
type of the pcap descriptor to the type specified by dlt.
pcap_set_datalink() returns 0 on success,
PCAP_ERROR_NOT_ACTIVATED if called on a capture handle that has
been created but not activated, or PCAP_ERROR on other errors. If
PCAP_ERROR is returned, pcap_geterr(3PCAP) or pcap_perror(3PCAP)
may be called with p as an argument to fetch or display the error
text.
