#define EAPI

#define EINA_UNUSED
#define EINA_WARN_UNUSED_RESULT
#define EINA_ARG_NONNULL(...)
#define EINA_DEPRECATED

 EINA_MALLOC is used to tell the compiler that a function may be treated as if any non-NULL pointer it returns cannot alias any other pointer valid when the function returns and that the memory has undefined content.
#define EINA_PURE
 EINA_PURE is used to tell the compiler this functions has no effects except the return value and their return value depends only on the parameters and/or global variables.

Define Documentation

#define EINA_ARG_NONNULL (   ...)

Used to warn when the specified arguments of the function are NULL.

Parameters:
...Oridnals of the parameters to check for nullity (1..n)
Returns:
Nothing, but Doxygen will complain if it's not documented :-P
#define EINA_C_ARRAY_LENGTH (   arr)    (sizeof(arr) / sizeof((arr)[0]))

Macro to return the array length of a standard c array. For example: int foo[] = { 0, 1, 2, 3 }; would return 4 and not 4 * sizeof(int).

Since (EFL) :
1.2.0
Examples:
eina_model_03.c, and eina_value_02.c.
#define EINA_COMPARE_CB (   function)    ((Eina_Compare_Cb)function)

Macro to cast to Eina_Compare_Cb.

#define EINA_DEPRECATED

Used to warn when the function is considered as deprecated.

#define EINA_EACH_CB (   Function)    ((Eina_Each_Cb)Function)

Macro to cast to Eina_Each.

#define EINA_FORMAT (   fmt)
Parameters:
fmtThe format to be used.
#define EINA_FREE_CB (   Function)    ((Eina_Free_Cb)Function)

Macro to cast to Eina_Free_Cb.

#define EINA_LIKELY (   exp)    exp
Parameters:
expThe expression to be used.
#define EINA_PRINTF (   fmt,
  arg 
)
Parameters:
fmtThe format to be used.
argThe argument to be used.
#define EINA_RANDOM_CB (   function)    ((Eina_Random_Cb)function)

Macro to cast to Eina_Random_Cb.

#define EINA_SCANF (   fmt,
  arg 
)
Parameters:
fmtThe format to be used.
argThe argument to be used.
#define EINA_SENTINEL

Attribute from gcc to prevent calls without the necessary NULL sentinel in certain variadic functions.

Since (EFL) :
1.7.0
#define EINA_UNLIKELY (   exp)    exp
Parameters:
expThe expression to be used.
#define EINA_UNUSED

Used to warn when an argument of the function is not used.

Used to warn when the returned value of the function is not used.


Typedef Documentation

Type to mimic a boolean.

Note:
it differs from stdbool.h as this is defined as an unsigned char to make it usable by bitfields (Eina_Bool name:1) and also take as few bytes as possible.

Function used in functions using sorting. It compares data1 and data2. If data1 is 'less' than data2, -1 must be returned, if it is 'greater', 1 must be returned, and if they are equal, 0 must be returned.

Examples:
eina_list_02.c.

A callback type used when iterating over a container.

A callback type used to free data when iterating over a container.

Function used in shuffling functions. An integer between min and max inclusive must be returned.
