Functions are organized according to the netCDF data model.

dispatch functions.
Dimensions	Dimensions are used to define the shape of data in netCDF
Variables	Variables hold multi-dimensional arrays of data
Attributes	Attributes hold metadata about data and files
Groups	NetCDF-4 added support for hierarchical groups within netCDF datasets
User-Defined Types	User defined types allow for more complex data structures
The Version 2 API	NetCDF's modern history began with the introduction of the V2 netCDF API by Glenn Davis and Russ Rew in 1991
Tutorial Examples	A more complex example of writing a netCDF file
NetCDF Error Handling	Each netCDF function in the C, Fortran 77, and Fortran 90 APIs returns 0 on success, in the tradition of C
