gai_strerrorW function (ws2tcpip.h)
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.
Syntax
WCHAR * gai_strerrorW(
[in] int ecode
);
Parameters
[in] ecode
Error code from the list of available getaddrinfo error codes. For a complete listing of error codes, see the getaddrinfo function.
Return value
None
Remarks
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 that 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 is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
