- * \brief Dynamic array structure.
- *
- * Before using the dynamic array, it must be initialized using da_initialize().
- * When getting individual items always use da_get_items() to obtain pointer to
- * the actual array.
- *
- * Items in the array cannot be dereferenced (it uses void * for storing the
- * the items). It is needed to type-cast the item array (obtained by calling
- * da_get_items()) to a proper type before dereferencing.
- *
- * When adding items, first reserve enough space for them by callling
- * da_reserve() and subsequently tell the array about the inserted items by
- * calling da_occupy(). When removing, the array must be told about the fact
- * by calling da_release().
- *
- * For getting the actual number of items in array use da_get_count().
- *
- * When the array is no more needed, the da_destroy() function must be called
- * before deallocating the structure.
