This header provides the Eet management functions.

Define Documentation

#define EET_DATA_DESCRIPTOR_ADD_ARRAY(edd, struct_type, name, member, subtype)

Value:

{   struct_type ___ett;     eet_data_descriptor_element_add(edd, name, EET_T_UNKNOW, EET_G_ARRAY,           (char *)(&(___ett.member)) - (char *)(&(___ett)),           /* 0,  */sizeof(___ett.member)/sizeof(___ett.member[0]), NULL, subtype);      }
Add a fixed size array type to a data descriptor.

Parameters:

edd The data descriptor to add the type to.
struct_type The type of the struct.
name The string name to use to encode/decode this member (must be a constant global and never change).
member The struct member itself to be encoded.
subtype The type of hash member to add.

This macro lets you easily add a fixed size array of other data types. All the parameters are the same as for EET_DATA_DESCRIPTOR_ADD_BASIC(), with the subtype being the exception. This must be the data descriptor of the element that is in each member of the hash to be stored.

Since:

1.0.2

#define EET_DATA_DESCRIPTOR_ADD_BASIC(edd, struct_type, name, member, type)

Value:

{   struct_type ___ett;     eet_data_descriptor_element_add(edd, name, type, EET_G_UNKNOWN,           (char *)(&(___ett.member)) - (char *)(&(___ett)),           0, /* 0,  */NULL, NULL);      }
Add a basic data element to a data descriptor.

Parameters:

edd The data descriptor to add the type to.
struct_type The type of the struct.
name The string name to use to encode/decode this member (must be a constant global and never change).
member The struct member itself to be encoded.
type The type of the member to encode.

This macro is a convenience macro provided to add a member to the data descriptor edd. The type of the structure is provided as the struct_type parameter (for example: struct my_struct). The name parameter defines a string that will be used to uniquely name that member of the struct (it is suggested to use the struct member itself). The member parameter is the actual struct member itself (for eet_dictionary_string_check * example: values), and type is the basic data type of the member which must be one of: EET_T_CHAR, EET_T_SHORT, EET_T_INT, EET_T_LONG_LONG, EET_T_FLOAT, EET_T_DOUBLE, EET_T_UCHAR, EET_T_USHORT, EET_T_UINT, EET_T_ULONG_LONG or EET_T_STRING.

typedef int(* Eet_Key_Password_Callback)(char *buffer, int size, int rwflag, void *data)

Callback used to request if needed the password of a private key.

Since:

2.0.0

Function Documentation

EAPI void eet_clearcache (void)

Clear eet cache.

Eet didn't free items by default. If you are under memory presure, just call this function to recall all memory that are not yet referenced anymore. The cache take care of modification on disk.

Since:

1.0.0

EAPI Eet_Error eet_close (Eet_File * ef)

Close an eet file handle and flush and writes pending.

Parameters:

ef A valid eet file handle.

This function will flush any pending writes to disk if the eet file was opened for write, and free all data associated with the file handle and file, and close the file.

If the eet file handle is not valid nothing will be done.

Since:

1.0.0

EAPI void* eet_data_descriptor_decode (Eet_Data_Descriptor * edd, const void * data_in, int size_in)

Decode a data structure from an arbitary location in memory.

Parameters:

edd The data descriptor to use when decoding.
data_in The pointer to the data to decode into a struct.
size_in The size of the data pointed to in bytes.

Returns:

NULL on failure, or a valid decoded struct pointer on success.

This function will decode a data structure that has been encoded using eet_data_descriptor_encode(), and return a data structure with all its elements filled out, if successful, or NULL on failure.

The data to be decoded is stored at the memory pointed to by data_in, and is described by the descriptor pointed to by edd. The data size is passed in as the value to size_in, ande must be greater than 0 to succeed.

This function is useful for decoding data structures delivered to the application by means other than an eet file, such as an IPC or socket connection, raw files, shared memory etc.

Please see eet_data_read() for more information.

Since:

1.0.0

EAPI void eet_data_descriptor_element_add (Eet_Data_Descriptor * edd, const char * name, int type, int group_type, int offset, int count, const char * counter_name, Eet_Data_Descriptor * subtype)

This function is an internal used by macros.

This function is used by macros EET_DATA_DESCRIPTOR_ADD_BASIC(), EET_DATA_DESCRIPTOR_ADD_SUB() and EET_DATA_DESCRIPTOR_ADD_LIST(). It is complex to use by hand and should be left to be used by the macros, and thus is not documented.

Since:

1.0.0

EAPI void* eet_data_descriptor_encode (Eet_Data_Descriptor * edd, const void * data_in, int * size_ret)

Encode a dsata struct to memory and return that encoded data.

Parameters:

edd The data descriptor to use when encoding.
data_in The pointer to the struct to encode into data.
size_ret A pointer to the an int to be filled with the decoded size.

Returns:

NULL on failure, or a valid encoded data chunk on success.

This function takes a data structutre in memory and encodes it into a serialised chunk of data that can be decoded again by 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, endianess etc.

The parameter edd must point to a valid data descriptor, and 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 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 size_ret points to is set to 0.

Please see eet_data_write() for more information.

Since:

1.0.0

EAPI void eet_data_descriptor_free (Eet_Data_Descriptor * edd)

This function frees a data descriptor when it is not needed anymore.

Parameters:

edd The data descriptor to free.

This function takes a data descriptor handle as a parameter and frees all data allocated for the data descriptor and the handle itself. After this call the descriptor is no longer valid.

Since:

1.0.0

EAPI Eet_Data_Descriptor* eet_data_descriptor_new (const char * name, int size, void *(*)(void *l) func_list_next, void *(*)(void *l, void *d) func_list_append, void *(*)(void *l) func_list_data, void *(*)(void *l) func_list_free, void(*)(void *h, int(*func)(void *h, const char *k, void *dt, void *fdt), void *fdt) func_hash_foreach, void *(*)(void *h, const char *k, void *d) func_hash_add, void(*)(void *h) func_hash_free)

Create a new empty data structure descriptor.

Parameters:

name The string name of this data structure (most be a global constant and never change).
size The size of the struct (in bytes).
func_list_next The function to get the next list node.
func_list_append The function to append a member to a list.
func_list_data The function to get the data from a list node.
func_list_free The function to free an entire linked list.
func_hash_foreach The function to iterate through all hash table entries.
func_hash_add The function to add a member to a hash table.
func_hash_free The function to free an entire hash table.

Returns:

A new empty data descriptor.

This function creates a new data descriptore and returns a handle to the new data descriptor. On creation it will be empty, containing no contents describing anything other than the shell of the data structure.

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-independant serialised data chunks for transmission across a a network or more.

The function pointers to the list and hash table functions are only needed if you use those data types, else you can pass NULL instead.

The pixel data is a linear array of pixels starting from the top-left of the image scanning row by row from left to right. Each pixel is a 32bit value, with the high byte being the alpha channel, the next being red, then green, and the low byte being blue. The width and height are measured in pixels and will be greater than 0 when returned. The alpha flag is either 0 or 1. 0 denotes that the alpha channel is not used. 1 denotes that it is significant. Compress is filled with the compression value/amount the image was stored with. The quality value is filled with the quality encoding of the image file (0 - 100). The lossy flags is either 0 or 1 as to if the image was encoded lossily or not.

On success the function returns a pointer to the image data decoded. The calling application is responsible for calling free() on the image data when it is done with it. On failure NULL is returned and the parameter values may not contain any sensible data.

EAPI void* eet_data_image_encode (const void * data, int * size_ret, unsigned int w, unsigned int h, int alpha, int compress, int quality, int lossy)

Encode image data for storage or transmission.

Parameters:

data A pointer to the image pixel data.
size_ret A pointer to an int to hold the size of the returned data.
w The width of the image in pixels.
h The height of the image in pixels.
alpha The alpha channel flag.
compress The compression amount.
quality The quality encoding amount.
lossy The lossiness flag.

Returns:

The encoded image data.

This function stakes image pixel data and encodes it with compression and possible loss of quality (as a trade off for size) for storage or transmission to another system.

The data expected is the same format as returned by eet_data_image_read. If this is not the case weird things may happen. Width and height must be between 1 and 8000 pixels. The alpha flags can be 0 or 1 (0 meaning the alpha values are not useful and 1 meaning they are). Compress can be from 0 to 9 (0 meaning no compression, 9 meaning full compression). This is only used if the image is not lossily encoded. Quality is used on lossy compression and should be a value from 0 to 100. The lossy flag can be 0 or 1. 0 means encode losslessly and 1 means to encode with image quality loss (but then have a much smaller encoding).

On success this function returns a pointer to the encoded data that you can free with free() when no longer needed.

EAPI void* eet_data_read (Eet_File * ef, Eet_Data_Descriptor * edd, const char * name)

Read a data structure from an eet file and decodes it.

Parameters:

ef The eet file handle to read from.
edd The data descriptor handle to use when decoding.
name The key the data is stored under in the eet file.

Returns:

A pointer to the decoded data structure.

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.

Returns:

An opened eet file handle.

This function will open an exiting eet file for reading, and build the directory table in memory and return a handle to the file, if it exists and can be read, and no memory errors occur on the way, otherwise NULL will be returned.

It will also open an eet file for writing. This will, if successful, delete the original file and replace it with a new empty file, till the eet file handle is closed or flushed. If it cannot be opened for writing or a memory error occurs, NULL is returned.

You can also open the file for read/write. If you then write a key that does not exist it will be created, if the key exists it will be replaced by the new data.

EAPI void* eet_read (Eet_File * ef, const char * name, int * size_ret)

Read a specified entry from an eet file and return data.

Parameters:

ef A valid eet file handle opened for reading.
name Name of the entry. eg: '/base/file_i_want'.
size_ret Number of bytes read from entry and returned.

Returns:

The data stored in that entry in the eet file.

This function finds an entry in the eet file that is stored under the name specified, and returns that data, decompressed, if successful. NULL is returned if the lookup fails or if memory errors are encountered. It is the job of the calling program to call free() on the returned data. The number of bytes in the returned data chunk are placed in size_ret.

If the eet file handle is not valid NULL is returned and size_ret is filled with 0.

EAPI const void* eet_read_direct (Eet_File * ef, const char * name, int * size_ret)

Read a specified entry from an eet file and return data.

Parameters:

ef A valid eet file handle opened for reading.
name Name of the entry. eg: '/base/file_i_want'.
size_ret Number of bytes read from entry and returned.

Returns:

The data stored in that entry in the eet file.

This function finds an entry in the eet file that is stored under the name specified, and returns that data if not compressed and successful. NULL is returned if the lookup fails or if memory errors are encountered or if the data is comrpessed. The calling program must never call free() on the returned data. The number of bytes in the returned data chunk are placed in size_ret.

If the eet file handle is not valid NULL is returned and size_ret is filled with 0.

EAPI int eet_write (Eet_File * ef, const char * name, const void * data, int size, int compress)

Write a specified entry to an eet file handle.

Parameters:

ef A valid eet file handle opened for writing.
name Name of the entry. eg: '/base/file_i_want'.
data Pointer to the data to be stored.
size Length in bytes in the data to be stored.
compress Compression flags (1 == compress, 0 = don't compress).

Returns:

Success or failure of the write.

This function will write the specified chunk of data to the eet file and return greater than 0 on success. 0 will be returned on failure.

The eet file handle must be a valid file handle for an eet file opened for writing. If it is not, 0 will be returned and no action will be performed.

Name, and data must not be NULL, and size must be > 0. If these conditions are not met, 0 will be returned.

The data will be copied (and optionally compressed) in ram, pending a flush to disk (it will stay in ram till the eet file handle is closed though).
