Overview

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.

Backward compatibility

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.
