That depends on whether /tmp/foo is a directory containing a file \0bar
or not. Since that is not a legal file name on POSIX systems, it should
return False. On Windows, I don't know whether such a file could exist or
not.

Fortunately, as Python programmers, we're not passing the string directly
to the libc call. We're passing a Python string to a Python function.
Nor are we receiving the result directly back from the libc call, since
it neither returns bool objects, nor raises exceptions on error.
