+
+ @section intro What is Eet?
+
+ It is a tiny library designed to write an arbitrary set of chunks of data
+ to a file and optionally compress each chunk (very much like a zip file)
+ and allow fast random-access reading of the file later on. It does not
+ do zip as a zip itself has more complexity than is needed, and it was much
+ simpler to implement this once here.
+
+ Eet is extremely fast, small and simple. Eet files can be very small and
+ highly compressed, making them very optimal for just sending across the
+ internet without having to archive, compress or decompress and install them.
+ They allow for lightning-fast random-access reads once created, making them
+ perfect for storing data that is written once (or rarely) and read many
+ times, but the program does not want to have to read it all in at once.
+
+ It also can encode and decode data structures in memory, as well as image
+ data for saving to Eet files or sending across the network to other
+ machines, or just writing to arbitrary files on the system. All data is
+ encoded in a platform independent way and can be written and read by any
+ architecture.
+
+ @section example A simple example on using Eet
+
+ Here is a simple example on how to use Eet to save a series of strings to a
+ file and load them again. The advantage of using Eet over just
+ fprintf() and
+ fscanf() is that not only can these entries be strings, they need no special
+ parsing to handle delimiter characters or escaping, they can be binary data,
+ image data, data structures containing integers, strings, other data
+ structures, linked lists and much more, without the programmer having to
+ worry about parsing, and best of all, Eet is very fast.
+
+ This is just a very simple example that doesn't show all of the capabilities
+ of Eet, but it serves to illustrate its simplicity.
+
+ @include eet-basic.c
+
+ @section compiling How to compile using Eet ?
+
+ Eet is a library your application links to. The procedure for this is very
+ simple. You simply have to compile your application with the appropriate
+ compiler flags that the @p pkg-config script outputs. For example:
+
+ Compiling C or C++ files into object files:
+
+ @verbatim
+ gcc -c -o main.o main.c `pkg-config --cflags eet`

+ Linking object files into a binary executable:

+ @verbatim
+ gcc -o my_application main.o `pkg-config --libs eet`
+ @endverbatim
+
+ You simply have to make sure that pkg-config is in your shell's PATH (see
+ the manual page for your appropriate shell) and eet.pc in /usr/lib/pkgconfig
+ or its path is in the PKG_CONFIG_PATH environment variable. It's that simple
+ to link and use Eet once you have written your code to use it.
+
+ Since the program is linked to Eet, it is now able to use any advertised
+ API calls to serialize your data.
+
+ You should make sure you add any extra compile and link flags to your
+ compile commands that your application may need as well. The above example
+ is only guaranteed to make Eet add it's own requirements.

+
+ After you understood what Eet is and installed it in your system you

+ (http://docs.enlightenment.org/auto/eina/) as it is very convenient
+ and optimized, and Eet provides integration with it.

+ *
+ * Functions to create, destroy and do basic manipulation of
+ * #Eet_File handles.
+ *
+ * This sections explains how to use the most basic Eet functions, which
+ * are used to work with eet files, read data from them, store it back in or
+ * take a look at what entries it contains, without making use of the
+ * serialization capabilities explained in @ref Eet_Data_Group.
+ *
+ * The following example will serve as an introduction to most, if not all,
+ * of these functions.
+ *
+ * If you are only using Eet, this is the only header you need to include.
+ * @dontinclude eet-file.c
+ * @skipline Eet.h
+ *
+ * Now let's create ourselves an eet file to play with. The following function
+ * shows step by step how to open a file and write some data in it.
+ * First, we define our file handler and some other things we'll put in it.
+ * @line static int
+ * @skip Eet_File
+ * @until ";
+ * @skip eet_open
+ *
+ * We open a new file in write mode, and if it fails, we just return, since
+ * there's not much more we can do about it..
+ * @until return
+ *
+ * Now, we need to write some data in our file. For now, strings will suffice,
+ * so let's just dump a bunch of them in there.
+ * @until }
+ *
+ * As you can see, we copied a string into our static buffer, which is a bit
+ * bigger than the full length of the string, and then told Eet to write it
+ * into the file, compressed, returning the size of the data written into the
+ * file.
+ * This is all to show that Eet treats data as just data. It doesn't matter
+ * what that data represents (for now), it's all just bytes for it. As running
+ * the following code will show, we took a string of around 30 bytes and put it
+ * in a buffer of 1024 bytes, but the returned size won't be any of those.
+ * @until printf
+ *
+ * Next, we copy into our buffer our set of strings, including their null
+ * terminators and write them into the file. No error checking for the sake
+ * of brevity. And a call to eet_sync() to make sure all out data is
+ * properly written down to disk, even though we haven't yet closed the file.
+ * @until eet_sync
+ *
+ * One more write, this time our large array of binary data and... well, I
+ * couldn't come up with a valid use of the last set of strings we stored,
+ * so let's take it out from the file with eet_delete().
+ * @until eet_delete
+ *
+ * Finally, we close the file, saving any changes back to disk and return.
+ * Notice how, if there's any error closing the file or saving its contents,
+ * the return value from the function will be a false one, which later on
+ * will make the program exit with an error code.
+ * @until return
+ *
+ * Moving onto our main function, we will open the same file and read it back.
+ * Trivial, but it'll show how we can do so in more than one way. We'll skip
+ * the variable declarations, as they aren't very different from what we've
+ * seen already.
+ *
+ * We start from the beginning by initializing Eet so things in general work.
+ * Forgetting to do so will result in weird results or crashes when calling
+ * any eet function, so if you experience something like that, the first thing
+ * to look at is whether eet_init() is missing.
+ * Then we call our @p create_eet_file function, described above, to make
+ * sure we have something to work with. If the function fails it will return
+ * 0 and we just exit, since nothing from here onwards will work anyway.
+ * @skip eet_init
+ * @until return
+ *
+ * Let's take a look now at what entries our file has. For this, we use
+ * eet_list(), which will return a list of strings, each being the name of
+ * one entry. Since we skipped before, it may be worth noting that @p list
+ * is declared as a @p char **.
+ * The @p num parameter will, of course, have the number of entries contained
+ * in our file.
+ * If everything's fine, we'll get our list and print it to the screen, and
+ * once done with it, we free the list. That's just the list, not its contents,
+ * as they are internal strings used by Eet and trying to free them will surely
+ * break things.
+ * @until }
+ *
+ * Reading back plain data is simple. Just a call to eet_read() with the file
+ * to read from, and the name of the entry we are interested in. We get back
+ * our data and the passed @p size parameter will contain the size of it. If
+ * the data was stored compressed, it will decompressed first.
+ * @until }
+ *
+ * Another simple read for the set of strings from before, except those were
+ * deleted, so we should get a NULL return and continue normally.
+ * @until }
+ *
+ * Finally, we'll get our binary data in the same way we got the strings. Once
+ * again, it makes no difference for Eet what the data is, it's up to us to
+ * know how to handle it.
+ * @until {
+ *
+ * Now some cheating, we know that this data is an Eet file because, well...
+ * we just know it. So we are going to open it and take a look at its insides.
+ * For this, eet_open() won't work, as it needs to have a file on disk to read
+ * from and all we have is some data in RAM.
+ *
+ * So how do we do? One way would be to create a normal file and write down
+ * our data, then open it with eet_open(). Another, faster and more efficient
+ * if all we want to do is read the file, is to use eet_memopen_read().
+ * @until memopen
+ *
+ * As you can see, the size we got from our previous read was put to good use
+ * this time. Unlike the first one where all we had were strings, the size
+ * of the data read only serves to demonstrate that we are reading back the
+ * entire size of our original @p buf variable.
+ *
+ * A little peeking to see how many entries the file has and to make an
+ * example of eet_num_entries() to get that number when we don't care about
+ * their names.
+ * @until printf
+ *
+ * More cheating follows. Just like we knew this was an Eet file, we also know
+ * what key to read from, and ontop of that we know that the data in it is not
+ * compressed.
+ * Knowing all this allows us to take some shortcuts.
+ * @until read_direct
+ *
+ * That's a direct print of our data, whatever that data is. We don't want
+ * to worry about having to free it later, so we just used eet_direct_read()
+ * to tell Eet to gives a pointer to the internal data in the file, without
+ * duplicating it. Since we said that data was not compressed, we shouldn't
+ * worry about printing garbage to the screen (and yes, we also know the data
+ * is yet another string).
+ * We also don't care about the size of the data as it was stored in the file,
+ * so we passed NULL as the size parameter.
+ * One very important note about this, however, is that we don't care about
+ * the size parameter because the data in the file contains the null
+ * terminator for the string. So when using Eet to store strings this way,
+ * it's very important to consider whether you will keep that final null
+ * byte, or to always get the size read and do the necessary checks and copies.
+ * It's up to the user and the particular use cases to decide how this will
+ * be done.
+ *
+ * With everything done, close this second file and free the data used to open
+ * it. And this is important, we can't free that data until we are done with
+ * the file, as Eet is using it. When opening with eet_memopen_read(), the data
+ * passed to it must be available for as long as the the file is open.
+ * @until }
+ *
+ * Finally, we close the first file, shutdown all internal resources used by
+ * Eet and leave our main function, thus terminating our program.
+ * @until return
+ *
+ * You can look at the full code of the example @ref eet-file.c "here".

+ * @defgroup Eet_Data_Group Eet Data Serialization
+ *
+ * Convenience functions to serialize and parse complex data
+ * structures to binary blobs.
+ *
+ * While Eet core just handles binary blobs, it is often required
+ * to save some structured data of different types, such as
+ * strings, integers, lists, hashes and so on.
+ *
+ * Eet can serialize and then parse data types given some
+ * construction instructions. These are defined in two levels:
+ *
+ * - #Eet_Data_Descriptor_Class to tell generic memory handling,
+ * such as the size of the type, how to allocate memory, strings,
+ * lists, hashes and so on.
+ *
+ * - #Eet_Data_Descriptor to tell inside such type, the members and
+ * their offsets inside the memory blob, their types and
+ * names. These members can be simple types or other
+ * #Eet_Data_Descriptor, allowing hierarchical types to be
+ * defined.
+ *
+ * Given that C provides no introspection, this process can be
+ * quite cumbersome, so we provide lots of macros and convenience
+ * functions to aid creating the types.
+ *
+ * We make now a quick overview of some of the most commonly used elements
+ * of this part of the library. A simple example of a configuration system
+ * will work as a somewhat real life example that is still simple enough to
+ * follow.
+ * Only the relevant sections will be shown here, but you can get the full
+ * code @ref eet-data-simple.c "here".
+ *
+ * Ignoring the included headers, we'll begin by defining our configuration
+ * struct.
+ * @dontinclude eet-data-simple.c
+ * @skip typedef
+ * @until }
+ *
+ * When using Eet, you don't think in matters of what data the program needs
+ * to run and which you would like to store. It's all the same and if it makes
+ * more sense to keep them together, it's perfectly fine to do so. At the time
+ * of telling Eet how your data is comprised you can leave out the things
+ * that are runtime only and let Eet take care of the rest for you.
+ *
+ * The key used to store the config follows, as well as the variable used to
+ * store our data descriptor.
+ * This last one is very important. It's the one thing that Eet will use to
+ * identify your data, both at the time of writing it to the file and when
+ * loading from it.
+ * @skipline MY_CONF
+ * @skipline Eet_Data_Descriptor
+ *
+ * Now we'll see how to create this descriptor, so Eet knows how to handle
+ * our data later on.
+ * Begin our function by declaring an Eet_Data_Descriptor_Class, which is
+ * used to create the actual descriptor. This class contains the name of
+ * our data type, its size and several functions that dictate how Eet should
+ * handle memory to allocate the necessary bits to bring our data to life.
+ * You, as a user, will very hardly set this class' contents directly. The
+ * most common scenario is to use one of the provided macros that set it using
+ * the Eina data types, so that's what we'll be doing across all our examples.
+ * @skip static void
+ * @until eet_data_descriptor_stream_new
+ *
+ * Now that we have our descriptor, we need to make it describe something.
+ * We do so by telling it which members of our struct we want it to know about
+ * and their types.
+ * The eet_data_descriptor_element_add() function takes care of this, but it's
+ * too cumbersome for normal use, so several macros are provided that make
+ * it easier to handle. Even with them, however, code can get very repetitive
+ * and it's not uncommon to define custom macros using them to save on typing.
+ * @skip #define
+ * @until }
+ *
+ * Now our descriptor knows about the parts of our structure that we are
+ * interesting in saving. You can see that not all of them are there, yet Eet
+ * will find those that need saving and do the right thing. When loading our
+ * data, any non-described fields in the structure will be zeroed, so there's
+ * no need to worry about garbage memory in them.
+ * Refer to the documentation of #EET_DATA_DESCRIPTOR_ADD_BASIC to understand
+ * what our macro does.
+ *
+ * We are done with our descriptor init function and it's proper to have the
+ * relevant shutdown. Proper coding guidelines indiciate that all memory
+ * allocated should be freed when the program ends, and since you will most
+ * likely keep your descriptor around for the life or your application, it's
+ * only right to free it at the end.

+/**
+ * @page eet_data_nested_example Nested structures and Eet Data Descriptors
+ *
+ * We've seen already a simple example of how to use Eet Data Descriptors
+ * to handle our structures, but it didn't show how this works when you
+ * have structures inside other structures.
+ *
+ * Now, there's a very simple case of this, for when you have inline structs
+ * to keep your big structure more organized, you don't need anything else
+ * besides what @ref eet-data-simple.c "this simple example does".
+ * Just use something like @p some_struct.sub_struct.member when adding the
+ * member to the descriptor and it will work.
+ *
+ * For example:
+ * @code
+ * typedef struct
+ * {
+ * int a_number;
+ * char *a_string;
+ * struct {
+ * int other_num;
+ * int one_more;
+ * } sub;
+ * } some_struct;
+ *
+ * void some_function()
+ * {
+ * ...
+ * my_desc = eet_data_descriptor_stream_new(&eddc);
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "a_number",
+ * a_number, EET_T_INT);
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "a_string",
+ * a_string, EET_T_STRING);
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "sub.other_num",
+ * sub.other_num, EET_T_INT);
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(my_desc, some_struct, "sub.one_more",
+ * sub.one_more", EET_T_INT);
+ * ...
+ * }
+ * @endcode
+ *
+ * But this is not what we are here for today. When we talk about nested
+ * structures, what we really want are things like lists and hashes to be
+ * taken into consideration automatically, and all their contents saved and
+ * loaded just like ordinary integers and strings are.
+ *
+ * And of course, Eet can do that, and considering the work it saves you as a
+ * programmer, we could say it's even easier to do than handling just integers.
+ *
+ * Let's begin with our example then, which is not all too different from the
+ * simple one introduced earlier.
+ *
+ * We won't ignore the headers this time to show how easy it is to use Eina
+ * data types with Eet, but we'll still skip most of the code that is not
+ * pertinent to what we want to show now, but as usual, you can get it full
+ * by following @ref eet-data-nested.c "this link".
+ *
+ * @dontinclude eet-data-nested.c
+ * @skipline Eina.h
+ * @skipline Eet.h
+ * @skip typedef struct
+ * @until } My_Conf_Subtype
+ *
+ * Extremely similar to our previous example. Just a new struct in there, and
+ * a pointer to a list in the one we already had. Handling a list of subtypes
+ * is easy on our program, but now we'll see what Eet needs to work with them
+ * (Hint: it's easy too).
+ * @skip _my_conf_descriptor
+ * @until _my_conf_sub_descriptor
+ *
+ * Since we have two structures now, it's only natural that we'll need two
+ * descriptors. One for each, which will be defined exactly as before.
+ * @skip static void
+ * @until eddc
+ * @skip EET_EINA_STREAM_DATA_DESCRIPTOR_CLASS_SET
+ * @until _my_conf_sub_descriptor
+ *
+ * We create our descriptors, each for one type, and as before, we are going to
+ * use a simple macro to set their contents, to save on typing.
+ * @skip #define
+ * @until EET_T_UCHAR
+ *
+ * So far, nothing new. We have our descriptors and we know already how to
+ * save them separately. But what we want is to link them together, and even
+ * more so, we want our main type to hold a list of more than one of the new
+ * sub type. So how do we do that?
+ *
+ * Simple enough, we tell Eet that our main descriptor will hold a list, of
+ * which each node will point to some type described by our new descriptor.
+ * @skip EET_DATA_DESCRIPTOR_ADD_LIST
+ * @until _my_conf_sub_descriptor
+ *
+ * And that's all. We are closing the function now so as to not leave dangling
+ * curly braces, but there's nothing more to show in this example. Only other
+ * additions are the necessary code to free our new data, but you can see it
+ * in the full code listing.
+ * @until }

+
+/**
+ * @page eet_data_file_descriptor Advanced use of Eet Data Descriptors
+ *
+ * A real life example is usually the best way to see how things are used,
+ * but they also involve a lot more code than what needs to be shown, so
+ * instead of going that way, we'll be borrowing some pieces from one in
+ * the following example. It's been slightly modified from the original
+ * source to show more of the varied ways in which Eet can handle our data.
+ *
+ * @ref eet-data-file_descriptor_01.c "This example" shows a cache of user
+ * accounts and messages received, and it's a bit more interactive than
+ * previous examples.
+ *
+ * Let's begin by looking at the structures we'll be using. First we have
+ * one to define the messages the user receives and one for the one he posts.
+ * Straight forward and nothing new here.
+ * @dontinclude eet-data-file_descriptor_01.c
+ * @skip typedef
+ * @until My_Post
+ *
+ * One more to declare the account itself. This one will contain a list of
+ * all messages received, and the posts we make ourselves will be kept in an
+ * array. No special reason other than to show how to use arrays with Eet.
+ * @until My_Account
+ *
+ * Finally, the main structure to hold our cache of accounts. We'll be looking
+ * for these accounts by their names, so let's keep them in a hash, using
+ * that name as the key.
+ * @until My_Cache
+ *
+ * As explained before, we need one descriptor for each struct we want Eet
+ * to handle, but this time we also want to keep around our Eet file and its
+ * string dictionary. You will see why in a moment.
+ * @skip Eet_Data_Descriptor
+ * @until _my_post_descriptor
+ * @skip Eet_File
+ * @until Eet_Dictionary
+ *
+ * The differences begin now. They aren't much, but we'll be creating our
+ * descriptors differently. Things can be added to our cache, but we won't
+ * be modifying the current contents, so we can consider the data read from
+ * it to be read-only, and thus allow Eet to save time and memory by not
+ * duplicating thins unnecessary.
+ * @skip static void
+ * @until _my_post_descriptor
+ *
+ * As the comment in the code explains, we are asking Eet to give us strings
+ * directly from the mapped file, which avoids having to load it in memory
+ * and data duplication.
+ * Of course, there are things to take into account when doing things this
+ * way, and they will be mentioned as we encounter those special cases.
+ *
+ * Next comes the actual description of our data, just like we did in the
+ * previous examples.
+ * @skip #define
+ * @until #undef
+ * @until #define
+ * @until #undef
+ *
+ * And the account struct's description doesn't add much new, but it's worth
+ * commenting on it.
+ * @skip #define
+ * @until _my_post_descriptor
+ *
+ * How to add a list we've seen before, but now we are also adding an array.
+ * There's nothing really special about it, but it's important to note that
+ * the EET_DATA_DESCRIPTOR_ADD_VAR_ARRAY is used to add arrays of variable
+ * length to a descriptor. That is, arrays just like the one we defined.
+ * Since there's no way in C to know how long they are, we need to keep
+ * track of the count ourselves and Eet needs to know how to do so as well.
+ * That's what the @p posts_count member of our struct is for. When adding
+ * our array member, this macro will look for another variable in the struct
+ * named just like the array, but with @p _count attached to the end.
+ * When saving our data, Eet will know how many elements the array contains
+ * by looking into this count variable. When loading back from a file, this
+ * variable will be set to the right number of elements.
+ *
+ * Another option for arrays is to use EET_DATA_DESCRIPTOR_ADD_ARRAY, which
+ * takes care of fixed sized arrays.
+ * For example, let's suppose that we want to keep track of only the last
+ * ten posts the user sent, and we declare our account struct as follows
+ * @code
+ * typedef struct
+ * {
+ * unsigned int id;
+ * const char *name;
+ * Eina_List *messages;
+ * My_Post posts[10];
+ * } My_Account;
+ * @endcode
+ * Then we would add the array to our descriptor with
+ * @code
+ * EET_DATA_DESCRIPTOR_ADD_ARRAY(_my_account_descriptor, My_Account, "posts",
+ * posts, _my_post_descriptor);
+ * @endcode
+ *
+ * Notice how this time we don't have a @p posts_count variable in our struct.
+ * We could have it for the program to keep track of how many posts the
+ * array actually contains, but Eet no longer needs it. Being defined that
+ * way the array is already taking up all the memory needed for the ten
+ * elements, and it is possible in C to determine how much it is in code.
+ * When saving our data, Eet will just dump the entire memory blob into the
+ * file, regardless of how much of it is really used. So it's important to
+ * take into consideration this kind of things when defining your data types.
+ * Each has its uses, its advantages and disadvantages and it's up to you
+ * to decide which to use.
+ *
+ * Now, going back to our example, we have to finish adding our data to the
+ * descriptors. We are only missing the main one for the cache, which
+ * contains our hash of accounts.
+ * Unless you are using your own hash functions when setting the descriptor
+ * class, always use hashes with string type keys.
+ * @skip #define
+ * @until }
+ *
+ * If you remember, we told Eet not to duplicate memory when possible at the
+ * time of loading back our data. But this doesn't mean everything will be
+ * loaded straight from disk and we don't have to worry about freeing it.
+ * Data in the Eet file is compressed and encoded, so it still needs to be
+ * decoded and memory will be allocated to convert it back into something we
+ * can use. We also need to take care of anything we add in the current
+ * instance of the program.
+ * To summarize, any string we get from Eet is likely to be a pointer to the
+ * internal dictionary, and trying to free it will, in the best case, crash
+ * our application right away.
+ *
+ * So how do we know if we have to free a string? We check if it's part of
+ * the dictionary, and if it's not there we can be sure it's safe to get
+ * rid of it.
+ * @skip static void
+ * @skip }
+ * @skip static void
+ * @until }
+ *
+ * See how this is used when adding a new message to our cache.
+ * @skip static My_Message
+ * @until return msg
+ * @until free(msg)
+ * @until }
+ *
+ * Skipping all the utility functions used by our program (remember you can
+ * look at the full example @ref eet-data-file_descriptor_01.c "here") we get to
+ * our cache loading code. Nothing out of the ordinary at first, just the
+ * same old open file, read data using our main descriptor to decode it
+ * into something we can use and check version of loaded data and if it doesn't
+ * match, do something accordingly.
+ * @skip static My_Cache
+ * @until }
+ * @until }
+ * @until }
+ *
+ * Then comes the interesting part. Remember how we kept two more global
+ * variables with our descriptors? One of them we already used to check if
+ * it was right to free a string or not, but we didn't know where it came from.
+ * Loading our data straight from the mmapped file means that we can't close
+ * it until we are done using it, so we need to keep its handler around until
+ * then. It also means that any changes done to the file can, and will,
+ * invalidate all our pointers to the file backed data, so if we add something
+ * and save the file, we need to reload our cache.
+ *
+ * Thus our load function checks if we had an open file, if there is it gets
+ * closed and our variable is updated to the new handler. Then we get the
+ * string dictionary we use to check if a string is part of it or not.
+ * Updating any references to the cache data is up you as a programmer to
+ * handle properly, there's nothing Eet can do in this situation.
+ * @until }
+ *
+ * The save function doesn't have anything new, and all that's left after it
+ * is the main program, which doesn't really have anything of interest within
+ * the scope of what we are learning.

+ * new data descriptor. On creation it will be empty, containing no contents
+ * describing anything other than the shell of the data structure.
+ * @param eddc The class from where to create the data descriptor.
+ * @return A handle to the new data descriptor.
+ *
+ * You add structure members to the data descriptor using the macros
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(), EET_DATA_DESCRIPTOR_ADD_SUB() and
+ * EET_DATA_DESCRIPTOR_ADD_LIST(), depending on what type of member you are
+ * adding to the description.
+ *
+ * Once you have described all the members of a struct you want loaded or
+ * saved, eet can load and save those members for you, encode them into
+ * endian-independent serialised data chunks for transmission across a
+ * a network or more.
+ *
+ * This function uses str_direct_alloc and str_direct_free. It is
+ * useful when the eet_data you are reading come from a file and
+ * have a dictionary. This will reduce memory use and improve the
+ * possibility for the OS to page this string out.
+ * However, the load speed and memory saving comes with some drawbacks to keep
+ * in mind. If you never modify the contents of the structures loaded from
+ * the file, all you need to remember is that closing the eet file will make
+ * the strings go away. On the other hand, should you need to free a string,
+ * before doing so you have to verify that it's not part of the eet dictionary.
+ * You can do this in the following way, assuming @p ef is a valid Eet_File
+ * and @p str is a string loaded from said file.
+ *
+ * @code
+ * void eet_string_free(Eet_File *ef, const char *str)
+ * {
+ * Eet_Dictionary *dict = eet_dictionary_get(ef);
+ * if (dict && eet_dictionary_string_check(dict, str))
+ * {
+ * // The file contains a dictionary and the given string is a part of
+ * // of it, so we can't free it, just return.
+ * return;
+ * }
+ * // We assume eina_stringshare was used on the descriptor
+ * eina_stringshare_del(str);
