Function Documentation

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

Returns
    A new lazy allocator.

  EINA_API void eina_lalloc_free (Eina_Lalloc * a)

Frees the resources for a lazy allocator.

Parameters
    a The lazy allocator to free.

References EINA_SAFETY_ON_NULL_RETURN.

  EINA_API Eina_Bool eina_lalloc_element_add (Eina_Lalloc * a)

Allocates one more of whatever the lazy allocator is allocating.

Parameters
    a The lazy allocator to add an item to.

Returns
    EINA_TRUE on success, else EINA_FALSE.

  EINA_API Eina_Bool eina_lalloc_elements_add (Eina_Lalloc * a, int num)

Adds several elements to a lazy allocator.

Parameters
    a The lazy allocator to add items to.
    num The number of elements to add.

Returns
    EINA_TRUE on success, else EINA_FALSE.
