No, they do no.
Embedded systems do not even have a file system, and some
operating systems (e.g. CMS, SINTRAN-III) have a sufficiently weird file
system to make directory operations targeted towards the UNIX, MS-DOS,
OS/2, VMS directory paradigms more or less useless.
There is a standard that do what you want. IEEE POSIX 1003.1 is an
_operating system_ interface standard, and defines how C should interface
to the operating system, including the interface to the directory.
To put the specification of that interface in the _language_ standard
would severely limit the scope of the language.
