The gai_strerror function assists in printing error messages based on the EAI_* errors returned by the getaddrinfo function. Note that the gai_strerror function is not thread safe, and therefore, use of traditional Windows Sockets functions such as the WSAGetLastError function is recommended.
Error code from the list of available getaddrinfo error codes. For a complete listing of error codes, see the getaddrinfo function.
If the ecode parameter is not an error code value that getaddrinfo returns, the gai_strerror function returns a pointer to a string that indicates an unknown error.
Note
The ws2tcpip.h header defines gai_strerror as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
