Reads a data structure from an eet file and decodes it using a cipher. 


\begin{DoxyParams}{Parameters}
{\em ef} & The eet file handle to read from. \\
\hline
{\em edd} & The data descriptor handle to use when decoding. \\
\hline
{\em name} & The key the data is stored under in the eet file. \\
\hline
{\em cipher\+\_\+key} & The key to use as cipher. \\
\hline
\end{DoxyParams}
\begin{DoxyReturn}{Returns}
A pointer to the decoded data structure.
\end{DoxyReturn}
This function decodes a data structure stored in an eet file, returning a pointer to it if it decoded successfully, or NULL on failure. This can save a programmer dozens of hours of work in writing configuration file parsing and writing code, as eet does all that work for the program and presents a program-\/friendly data structure, just as the programmer likes. Eet can handle members being added or deleted from the data in storage and safely zero-\/fills unfilled members if they were not found in the data. It checks sizes and headers whenever it reads data, allowing the programmer to not worry about corrupt data.

Once a data structure has been described by the programmer with the fields they wish to save or load, storing or retrieving a data structure from an eet file, or from a chunk of memory is as simple as a single function call.

The data to be decoded is stored at the memory pointed to by {\ttfamily data\+\_\+in}, and is described by the descriptor pointed to by {\ttfamily edd}. The data size is passed in as the value to {\ttfamily size\+\_\+in}, and must be greater than 0 to succeed.

This function takes a data structure in memory and encodes it into a serialised chunk of data that can be decoded again by \mbox{\hyperlink{group__Eet__Data__Group_gaa050d172c60add6af4bbc30fc672f960}{eet\+\_\+data\+\_\+descriptor\+\_\+decode()}}. This is useful for being able to transmit data structures across sockets, pipes, IPC or shared file mechanisms, without having to worry about memory space, machine type, endianness etc.

The parameter {\ttfamily edd} must point to a valid data descriptor, and {\ttfamily data\+\_\+in} must point to the right data structure to encode. If not, the encoding may fail.

On success a non NULL valid pointer is returned and what {\ttfamily size\+\_\+ret} points to is set to the size of this decoded data, in bytes. When the encoded data is no longer needed, call free() on it. On failure NULL is returned and what {\ttfamily size\+\_\+ret} points to is set to 0.
