Most of the functions in CRT are available for Metro style apps. Those that are not available will be aytomatically hidden by the appropriate macros (WINAPI_FAMILY etc.). However, I must mention that most of the files API will work only in specific
locations where Windows allows access to apps. CRT API will work within the boundaries that Windows has for accessing OS resources (like files, directories, settings, handles etc.) at runtime.
