7.7 Architecture of NetCDF APIs and Libraries
Knowing how netCDF APIs are layered is sometimes useful for
understanding performance and error handling.
Layering architecture of netCDF C/C++/Fortran libraries and
applications:
- The C and Java implementations are independent. Java is not
shown here.
- All non-Java APIs call the C library.
- The v2 layer is supported for backward compatibility, but is
just a layer which calls the classic API.
- Utilities ncdump, ncgen, and nccopy are written in
C. (nc-config is a Bourne shell script, constructed by the netCDF
configure script.
- The Fortran-90 library calls C library through Fortran 77 API, which
is a severe limitation for netCDF-4. Plans call for it to rewritten
to use the Fortran 2003 C interoperability layer.
