<h2>ncgen</h2>
<code>ncgen [-b] [-c] [-f] [-n] [-o <i>output_file</i>]
<i>input_file</i></code><p>
Where:<p>
<ul>
<code>-b</code> Create a (binary) netCDF file. If the <code>-o</code>
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 <code>.nc</code> extension. If a file
already exists with the specified name, it will be
overwritten.<p>
<code>-c</code> Generate C source code that will create a netCDF
file
matching the netCDF specification. The C source code
is written to standard output.<p>
<code>-f</code> Generate Fortran source code that will create a
netCDF
file matching the netCDF specification. The Fortran
source code is written to standard output. <p>
<code>-o
<i>outputfile</i></code><br>
<ul>
Name for the netCDF file created. If this option is
specified, it implies the <code>-b</code> option. (This
option is
necessary because netCDF files cannot be written
directly to standard output, since standard output is
not seekable.)</ul><p>
<code>-n</code> Like <code>-b</code> option, except creates netCDF
file with the obsolete <code>.cdf</code> extension instead of the
<code>.nc</code> extension,
in the absence of an output filename specified by the
<code>-O</code> option. This option is only supported for
backward
compatibility.</ul></ul><p>
<h3>Examples</h3>
<ol>
<li>Check the syntax of the CDL file <code>foo.cdl</code>:<p>
<dd><code>ncgen foo.cdl</code><p>
<li>
From the CDL file <code>foo.cdl</code>, generate an equivalent binary
netCDF file named <code>x.nc</code>:<p>
<dd><code>ncgen -o x.nc foo.cdl</code><p>
<li>
From the CDL file <code>foo.cdl</code>, generate a C program containing
the netCDF function invocations necessary to create an
equivalent binary netCDF file named <code>x.nc</code>:<p>
<dd><code>ncgen -c -o x.nc foo.cdl</code></ol>
