#include <pcap/pcap.h>

const char *pcap_strerror(int error);

This function returns an error message string corresponding to error . It uses either strerror (3) or its thread-safe variant if one is available, which currently is the case in every supported OS. This function was not thread-safe in libpcap before 1.8.1 on Windows and in libpcap before 1.10.5 on all other OSes. pcap (3PCAP)
