+/** @file
+ File statistics (using stat() and
+ lstat() functions, wchar_t).
+
+ Note: The stat() and lstat() functions are sufficient for
+ non-Windows systems.
+ On Windows systems the st_dev and st_ino components may contain
+ dummy contents, the stat structure does not contain information
+ about symbolic links.
+
+ For a portable (both Windows and non-Windows) check whether a file
+ is a symbolic link, reparse point... use the dk4_file_info_t
+ data type from dk4fileit.h and the functions from dk4filei.h.
+
+ CRT on Windows: Required.
