Question
void dict_clear (dict_t* dict);
This function clears the dictionary dict, destroying each pair key/value, but does not destroy dict itself (remember that dict was allocated using dict_create, so it will need to be freed at some point, but this is not this function’s job.)
This is now the function that frees (destroys) a dictionary:
void dict_destroy (dict_t* dict);
This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash).
This simple function returns the current size of the dictionary:
size_t dict_size (const dict_t* dict);
