/**
|
|
* @def EINA_LIST_ITER_NEXT
|
|
* @brief Macro to iterate over a list easily.
|
|
*
|
|
* @param list The list to iterate over.
|
|
* @param l A list that is used as loop index.
|
|
* @param data The data
|
|
*
|
|
* This macro allow the iteration over @p list in an easy way. It
|
|
* iterates from the first element to the last one. @p data is the
|
|
* data of each element of the list. @p l is an #Eina_List that is
|
|
* used as counter.
|
|
*
|
|
* This macro can be used for freeing the data of alist, like in
|
|
* the following example:
|
|
*
|
|
* @code
|
|
* Eina_List *list;
|
|
* Eina_List *l;
|
|
* char *data;
|
|
*
|
|
* // list is already filled,
|
|
* // its elements are just duplicated strings,
|
|
* // EINA_LIST_ITER_NEXT will be used to free those strings
|
|
*
|
|
* EINA_LIST_ITER_NEXT(list, l, data)
|
|
* free(data);
|
|
* @endcode
|
