GetKeyboardLayoutNameW function (winuser.h)
Retrieves the name of the active input locale identifier (formerly called the keyboard layout) for the calling thread.
[out] LPWSTR pwszKLID
The buffer (of at least KL_NAMELENGTH characters in length) that receives the name of the input locale identifier, including the terminating null character. This will be a copy of the string provided to the LoadKeyboardLayout function, unless layout substitution took place.
For a list of the input layouts that are supplied with Windows, see Keyboard Identifiers and Input Method Editors for Windows.
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The input locale identifier is a broader concept than a keyboard layout, since it can also encompass a speech-to-text converter, an Input Method Editor (IME), or any other form of input.
Beginning in Windows 8: The preferred method to retrieve the language associated with the current keyboard layout or input method is a call to Windows.Globalization.Language.CurrentInputMethodLanguageTag. If your app passes language tags from CurrentInputMethodLanguageTag to any National Language Support functions, it must first convert the tags by calling ResolveLocaleName.
The winuser.h header defines GetKeyboardLayoutName 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.
