function varargout = coda_fieldcount(varargin)
% CODA_FIELDCOUNT Retrieve the number of fields for a record in a
% product file.
%
% N = CODA_FIELDCOUNT(CODA_FILE_ID, <DATA SPEC ARGS>) returns the
% number of fields for the struct that would be returned if coda_fetch
% would have been called with the same arguments. The last item of the
% data specifier argument should point to a record.
%
% The coda_file_id parameter must be a valid CODA file handle that was
% retrieved with coda_open. The format for the data specification
% argument list <data spec args> is described in the help page for
% coda_param.
%
% See also CODA_FETCH, CODA_OPEN, CODA_PARAM
%
% Call CODA_MATLAB.MEX to do the actual work.
