Never mind rename.  Just help the user as best you can.  This isn't hard.

Hi Dave,

 Is there a method to find the filename of an open netcdf file from the
 ncid.  The method ncinquire does not provide it.

No, there's no way to determine the name with which a file was opened
from the netCDF C, Fortran, or C++ API's.

If there was a way to get the file name, it would be wrong if the file
was renamed by another process after it was opened.  Maybe that's the
reason no such function exists.  Similarly, I think it's also not
possible to determine the name of the file associated with a file
descriptor returned by the Unix open() call (please correct me if I'm
wrong about this).
