Usage

This library has, (at the v1.0) 4 functions :

int hashmap_has(struct hashmap *map, const char *key);
int hashmap_del(struct hashmap **map, const char *key, void (*fr)(void *));
int hashmap_add(struct hashmap **map, const char *key, void *data);
void *hashmap_get(struct hashmap *map, const char *key);
void hashmap_free(struct hashmap *map, void (*free_it)(void *));

This functions helps you manage your Hashmap all way along.

HASHMAP_HAS

This simple function takes in a map and a key in parameter.

it will search for the occurence of the key in the hashmap and return 1 if it exists, 0 ortherwise.

---

HASHMAP_DEL

This simple function takes in a map and a key in parameter.

it will destroy the element specified by key in the hashmap and return 0 in case of success, 1 ortherwise.

---

HASHMAP_ADD

This simple function takes in a map, a key and a data in parameter.

It will save the data using the key as the way to get it with the next function.

---

HASHMAP_GET

This simple function takes in a map and a key in parameter.

it will get the (void *) pointer on the data given the key it was added before with.

---

This simple function takes in a map and a function pointer in parameter.

it will free the hashmap using the function pointer on data.
