The function nc_inq_format, documented here:
http://www.unidata.ucar.edu/netcdf/docs/netcdf-c.html#nc_005finq-Family
returns a value indicating the netCDF format variant of the file.
Also if you use
ncdump -s filename
the output includes a virtual global attribute, "_Format", that
specifies what type the file is. The "-s" option is intended to
... provide performance-related information about the file format and
variable properties for netCDF-4 data. These special virtual
attributes are not actually part of the data, they are merely a
convenient way to display miscellaneous properties of the data in CDL
(and eventually NcML). They include `_ChunkSizes', `_DeflateLevel',
`_Endianness', `_Fletcher32', `_Format', `_NoFill', `_Shuffle', and
`_Storage'.
