It affects the C++ library functions and optional also the C standard library functions. See http://www.cplusplus.com/reference/locale/locale/global/[^].

To set a locale for the Windows API functions, use SetThreadLocale[^].

For MFC it depends. Some MFC controls like CComboBox provide a SetLocale member function to select a different locale. The CString classes use the standard C libraries for formatting and are therefore affected by setlocale.
