Hi Matt,

The Fortran-90 Users Guide at 

  http://www.unidata.ucar.edu/packages/netcdf/f90/Documentation/f90-html-docs/

is the most up-to-date, with some extra sections and more correct
information on writing netCDF files larger than 2 Gbytes.  The latest
C, Fortran-77, and C++ documentation is still from 1997,
unfortunately, but those interfaces haven't changed since then.  There
is a good up-to-date netCDF Java User Manual at

  http://www.unidata.ucar.edu/packages/netcdf-java/v2.1/NetcdfJavaUserManual.htm

> Is there any code samples or tutorials on the ucar site?

No tutorials, and very few examples.  On my to-do list is developing
some exemplary examples for new users to supplement the documentation.
The Fortran-90 Users Guide has more complete examples that the C or
Fortran-77 guides, which have fragmentary examples with each section.
There is a C++ example in the distribution in src/cxx/example.cpp

You should also look at 

  http://www.unidata.ucar.edu/packages/netcdf/BestPractices.html

to see some Best Practices for creating netCDF files.

One way to get a simple example is to just cut and paste the example
CDL file from Chapter 2 of the User's Guide, that starts

  netcdf example_1 {  // example of CDL notation for a netCDF dataset

  dimensions:         // dimension names and lengths are declared first
          lat = 5, lon = 10, level = 4, time = unlimited;

and put it in a file named example_1.cdl.  Then to see an example of a
C program that would create the corresponding netCDF file, just run

  ncgen -c example_1.cdl > example_1.c

and similarly for Fortran and "ncgen -f".  You can do the same with
CDL files you create yourself.
