Function Documentation

eina_lalloc_new()

EINA_API Eina_Lalloc * eina_lalloc_new	(	void *	data,
		Eina_Lalloc_Alloc	alloc_cb,
		Eina_Lalloc_Free	free_cb,
		int	num_init
	)

Creates a new lazy allocator.

Parameters

[in]	data	The data for which memory will be allocated.
[in]	alloc_cb	The callback to allocate memory for data items.
[in]	free_cb	The callback to free memory for data items.
[in]	num_init	The number of data items to initially allocate space for.

Returns

A new lazy allocator.

eina_lalloc_free()

EINA_API void eina_lalloc_free

(

Eina_Lalloc *

a

)

Frees the resources for a lazy allocator.

Parameters

[in,out]

a

The lazy allocator to free.

References EINA_SAFETY_ON_NULL_RETURN.

eina_lalloc_element_add()

EINA_API Eina_Bool eina_lalloc_element_add

(

Eina_Lalloc *

a

)

Allocates one more of whatever the lazy allocator is allocating.

Parameters

[in,out]

a

The lazy allocator to add an item to.

Returns

EINA_TRUE on success, else EINA_FALSE.

References EINA_FALSE, EINA_SAFETY_ON_NULL_RETURN_VAL, and EINA_TRUE.

eina_lalloc_elements_add()

EINA_API Eina_Bool eina_lalloc_elements_add	(	Eina_Lalloc *	a,
		int	num
	)

Adds several elements to a lazy allocator.

Parameters

[in,out]	a	The lazy allocator to add items to.
[in]	num	The number of elements to add.

Returns

EINA_TRUE on success, else EINA_FALSE.
