Inline array is a container that stores the data itself, not the pointers to the data.
- Since (EFL) :
- 1.2
This means there is no memory fragmentation, also for small data types (such as char, short, int, and so on) it's more memory efficient.
Usage of the inline array is very similar to that of other Containers, like all arrays adding elements to the beginning of the array is a lot more costly than appending, so those operations should be minimized.

for ((itr) = (array)->members; \
(itr) < (((__typeof__(*itr)*)(array)->members) + (array)->len); \
(itr)++)
Walks through an array linearly from head to tail.
- Parameters:
-
[in] array The array object [in] itr An iterator pointer
- Note:
itr
must be a pointer with sizeof(itr*) == array->member_size.-
This is fast as it does direct pointer access, but it does not check for
NULL
pointers or invalid array objects. Use eina_inarray_foreach() to do that. - Do not modify an array as you walk through it. If that is desired, then use eina_inarray_foreach_remove().
- Since (EFL) :
- 1.2
- Examples:
- eina_inarray_01.c, eina_inarray_02.c, and eina_inarray_03.c.

Function Documentation
Eina_Accessor* eina_inarray_accessor_new | ( | const Eina_Inarray * | array | ) |
Returns a new accessor associated to an array.
This function returns a newly allocated accessor associated to array
.
- Parameters:
-
[in] array The array object
- Returns:
- A new accessor
- Note:
- If the memory cannot be allocated,
NULL
is returned Otherwise, a valid accessor is returned.

void* eina_inarray_alloc_at | ( | Eina_Inarray * | array, |
unsigned int | position, | ||
unsigned int | member_count | ||
) |
Opens a space at the given position, returning its pointer.
- Parameters:
-
[in] array The array object [in] position The position to insert first member at (open/allocate space) [in] member_count The number of times member_size
bytes are allocated
- Returns:
- A pointer to the first member memory allocated, otherwise
NULL
on errors
- Note:
- This is similar to eina_inarray_insert_at(), but useful if the members contents are still unknown or unallocated. It makes room for the required number of items and returns the pointer to the first item, similar to malloc(member_count * member_size), with the guarantee that all the memory is within the members array.
- The new member memory is undefined, it's not automatically zeroed.
- All the members from position to the end of the array are shifted to the end.
- If position is equal to the end of the array (equal to eina_inarray_count()), then the member is appended.
- If position is bigger than the array length, it fails.
