void freelist_delete( struct freelist_state *fs, void (*user_data_delete_function)(void *user_data, void *user_state), void *user_state );
struct freelist_state *fs
- A freelist state as allocated by freelist_new.
void (*user_data_delete_function)(void *user_data, void *user_state)
- A callback function, which can be NULL. This function is called with the user data void pointer from each element before that element is deleted, giving the user an opportunity to delete any allocated state.
- This pointer is passed into the user_data_delete_function as its second argument, enabling the caller to pass state into the callback function.
No return value.
This function deletes the freelist. Any elements which have been popped and not returned to the freelist will be memory leaked when this function is called. As such, it is obviously necessary to ensure all elements are pushed onto the freelist before deleting the freelist.
