C++ interface problems

[Gregory Orris <orris@xxxxxxxxxxxxxxxxxx>]

All,

Currently I'm trying to use the libnetcdf_c++.a interface in a fairly 
simple program on an SGI OCTANE running IRIX 6.5.3.  While everything
has been compiled and the tests check out fine, a bug has cropped up that
is inexplicable:  The following lines of code 

cerr << "Is it valid?  " << output_file.is_valid() << endl;
cerr << "What is the id?  " << output_file.id() << endl;
cerr << "Is Latitude valid? " << output_file.get_var("Latitude")->is_valid() << 
endl;

elicits the following output

Is it valid?  1
What is the id?  3
ncvarid: ncid 3: Not a netCDF id

Any hints?

Thanks in advance....
