% DATA FUNCTIONS

\subsection*{A.5  Data Mode Functions}

Recall that the data mode functions are split into the High Level data mode interface and the
Flexible data mode interface.

\subsubsection*{A.5.1  High Level Data Mode Interface}

The High Level functions most closely mimic the original NetCDF data mode interface.

% \emph{What about the single variable and varm functions?  Are they important?}

\input data_mode_api

\subsubsection*{A.5.2  Flexible Data Mode Interface}

Note that there are considerably fewer functions in the flexible data mode
inteface, because these functions can handle all different types with the same
call.  All of the high level functions are written in terms of these
functions.

\input flexible_api

\subsubsection*{A.5.3  Multiple Variable Data Mode Interface}

\input multiple_io

\subsubsection*{A.5.4  Nonblocking Data Mode Interface}

\input nonblocking
