Win32 version of fcntl(..., F_DUPFD. ...)?

Win32 has _open(), _open_osfhandle(), etc. - but is there a Win32 version of fcntl(..., F_DUPFD. ...) which can duplicate a given file descriptor, and uses the lowest available file descriptor GREATER OR EQUAL than the given arg (e.g. this is NOT Win32 _dup() or _dup2()!!)?

I'm basically looking for the Linux/Solaris/Illumos implementation of this fcntl() function for Win32, or emulation code:

   F_DUPFD (int)
          Duplicate the file descriptor fd using the lowest-numbered
          available file descriptor greater than or equal to arg.
          This is different from dup2(2), which uses exactly the
          file descriptor specified.
