/**
* @page Example_Eet_Data_File_Descriptor_02 File descriptor data example, with Eet unions and variants
*
* This is an example much like the one shown in @ref
* eet_data_file_descriptor. The difference is that here we're
* attaining ourselves to two new data types to store in an Eet file
* -- @b unions and @b variants. We don't try to come with data
* mapping to real world use cases, here. Instead, we're defining
* 3 different simple structures to be used throughout the example:
* @dontinclude eet-data-file_descriptor_02.c
* @skip typedef struct _Example_Struct1
* @until typedef struct _Example_Struct3
* @skip struct _Example_Struct1
* @until int body
* @until };
*
* To identify, for both union and variant data cases, the type of
* each chunk of data, we're defining types to point to each of those
* structs:
* @dontinclude eet-data-file_descriptor_02.c
* @skip typedef enum _Example_Data_Type
* @until ;
* @skip enum _Example_Data_Type
* @until };
*
* We have also a mapping from those types to name strings, to be used
* in the Eet unions and variants @c type_get() and @c type_set() type
* identifying callbacks:
* @skip struct
* @until };
*
* In this example, we have no fancy hash to store our data into
* profiles/accounts, but just two lists for union and variant data
* nodes:
* @dontinclude eet-data-file_descriptor_02.c
* @skip typedef struct _Example_Lists
* @until typedef struct _Example_Lists
* @skip struct _Example_Lists
* @until };
*
* Let's begin with our unions, then, which look like:
* @dontinclude eet-data-file_descriptor_02.c
* @skip typedef struct _Example_Union
* @until typedef struct _Example_Union
* @skip struct _Example_Union
* @until };
*
* The first interesting part of the code is where we define our data
* descriptors for the main lists, the unions and all of structures
* upon which those two depend.
* @dontinclude eet-data-file_descriptor_02.c
* @skip declaring types
* @until _union_descriptor);
* The code for descriptors on @c Example_Struct1, @c Example_Struct2
* and @c Example_Struct3 is straightforward, a matter already covered
* on @ref eet_data_file_descriptor. What is new, here, are the two
* type matching functions for our unions. There, we must set the @c
* data pointer to its matching type, on @c _union_type_set and return
* the correct matching type, on @c _union_type_get:
* @dontinclude eet-data-file_descriptor_02.c
* @skip union type_get()
* @until _union_type_set
* @until _union_type_set
*
* With the #EET_DATA_DESCRIPTOR_ADD_MAPPING calls, which follow, we
* make the the link between our type names and their respective
* structs. The code handling actual data is pretty much the same as in
* @ref eet_data_file_descriptor -- one uses command line arguments to
* enter new data chunks (or just to visualize the contents of an Eet
* file), signalling if they are unions or variants. One must also
* pass the type of the data chuck to enter, with integers 1, 2 or
* 3. Then, come the fields for each type:
* @dontinclude eet-data-file_descriptor_02.c
* @skip Usage
* @until argv
*
* Variants are very similar to unions, except that data chunks need
* @b not contain previously allocated space for each of the possible
* types of data going in them:
* @dontinclude eet-data-file_descriptor_02.c
* @skip typedef struct _Example_Variant
* @until typedef struct _Example_Variant
* @skip struct _Example_Variant_Type
* @until };
* @until };
*
* The code declaring the data descriptors and handling the data is
* very similar to the unions part, and is left for the reader to
* check for him/herself. The complete code of the example follows.
*
* @includelineno eet-data-file_descriptor_02.c
* @example eet-data-file_descriptor_02.c
*/
/**
* @page Example_Eet_Data_Cipher_Decipher Eet data cipher/decipher example
*
* In this example, we exemplify the usage of eet_write_cipher() and
* eet_read_cipher(). For it to work, <b>make sure</b> to have your
* Eet installation with a ciphering backend enabled.
*
* We start by defining the information to record in an Eet file (@c
* buffer), the key to cipher that (@c key) and a dummy wrong key to
* try to access that information, later (@c key_bad).
* @dontinclude eet-data-cipher_decipher.c
* @skip buffer =
* @until bad =
*
* After opening our file, we simply use the first cited function to
* write our string ciphered:
* @dontinclude eet-data-cipher_decipher.c
* @skip eet_open
* @until eet_close
*
* Then, after closing it on purpose, we open it again, to retrieve
* the encrypted information back, in a readable format:
* @skip eet_open
* @until eet_close
* @until eet_close
*
* Note that we do it twice, being the last time with the wrong
* key. In this last case, if the information is read back and matches
* the original @c buffer, something wrong is going on (we made it to
* fail on purpose). The former access is OK, and must work.
*
* What we do in sequence is just to delete the file. The complete
* code of the example follows.
*
* @includelineno eet-data-cipher_decipher.c
* @example eet-data-cipher_decipher.c
