GetUserDefaultLocaleName function (winnls.h)
Retrieves the user default locale name.
int GetUserDefaultLocaleName( [out] LPWSTR lpLocaleName, [in] int cchLocaleName );
Pointer to a buffer in which this function retrieves the locale name.
Size, in characters, of the buffer indicated by lpLocaleName. The maximum possible length of a locale name, including a terminating null character, is LOCALE_NAME_MAX_LENGTH. This is the recommended size to supply in this parameter.
Returns the size of the buffer containing the locale name, including the terminating null character, if successful.
The function returns 0 if it does not succeed. To get extended error information, the application can call GetLastError, which can return one of the following error codes:
- ERROR_INSUFFICIENT_BUFFER. A supplied buffer size was not large enough, or it was incorrectly set to NULL.
This function can retrieve data from custom locales. Data is not guaranteed to be the same from computer to computer or between runs of an application. If your application must persist or transmit data, see Using Persistent Locale Data.
