Do you have access to a UNIX system?  If so, then you could copy
fills.nc there and either compare it to the one from the netCDF 
distribution or use ncdump on the UNIX system to examine the file.
The output should look like this:

    % ncdump fills.nc
    netcdf fills {
    dimensions:
            n = 2 ;
    variables:
            double d(n) ;
            float f(n) ;
            long l(n) ;
            short s(n) ;
            byte b(n) ;

    data:

     d = 1, _ ;

     f = 1 , _ ;

     l = 1, _ ;

     s = 1, _ ;

     b = 1, -127 ;
    }

It's possible that the isprint() function on your system is acutally a
macro (this would be non-standard).  Would ypu please send me the above
line after the source code has been passed through the C preprocessor,
e.g.

    $ cc/preprocess_only=ncdump.i/incl=[-.libsrc] ncdump.i
