ncgen

Where:

-b
Create a (binary) netCDF file. If the -o option is absent, a default file name will be constructed from the netCDF name (specified after the netcdf keyword in the input) by appending the .nc extension. If a file already exists with the specified name, it will be overwritten.

-c

Generate C source code that will create a netCDF file matching the netCDF specification. The C source code is written to standard output.

-f

Generate Fortran source code that will create a netCDF file matching the netCDF specification. The Fortran source code is written to standard output.

-o outputfile

Name for the netCDF file created. If this option is specified, it implies the -b option. (This option is necessary because netCDF files cannot be written directly to standard output, since standard output is not seekable.)

-n

Like -b option, except creates netCDF file with the obsolete .cdf extension instead of the .nc extension, in the absence of an output filename specified by the -O option. This option is only supported for backward compatibility.

Examples

1. Check the syntax of the CDL file foo.cdl:
   ncgen foo.cdl

   From the CDL file foo.cdl, generate an equivalent binary netCDF file named x.nc:

   ncgen -o x.nc foo.cdl

   From the CDL file foo.cdl, generate a C program containing the netCDF function invocations necessary to create an equivalent binary netCDF file named x.nc:

   ncgen -c -o x.nc foo.cdl
