Extensions peculiar to a particular operating system are also available through
the :mod:`os` module, but using them is of course a threat to portability!

+ inaccessible file names and paths, or other arguments that have the correct
+ type, but are not accepted by the operating system.
.. exception:: error
- .. index:: module: errno
-
- This exception is raised when a function returns a system-related error (not for
- illegal argument types or other incidental errors). This is also known as the
- built-in exception :exc:`OSError`. The accompanying value is a pair containing
- the numeric error code from :cdata:`errno` and the corresponding string, as
- would be printed by the C function :cfunc:`perror`. See the module
- :mod:`errno`, which contains names for the error codes defined by the underlying
- operating system.
-
- When exceptions are classes, this exception carries two attributes,
- :attr:`errno` and :attr:`strerror`. The first holds the value of the C
- :cdata:`errno` variable, and the latter holds the corresponding error message
- from :cfunc:`strerror`. For exceptions that involve a file system path (such as
- :func:`chdir` or :func:`unlink`), the exception instance will contain a third
- attribute, :attr:`filename`, which is the file name passed to the function.
