Something like as\_intmap\_set\_map(p\_map, 12 , p\_value)?

as\_map has a generic key, value function, which can take any type

int as\_hashmap\_set(as\_hashmap \* map, const as\_val \* key, const as\_val \* val);

</div>

Code below:

static inline int as\_int64map\_set\_int64(as\_map \* m, int64\_t k, int64\_t v)

{

```
 return as_util_hook(set, 1, m, (as_val *) as_integer_new(k), (as_val *) as_integer_new(v));

```

}

static inline int64\_t as\_int64map\_get\_int64(as\_map \* m, int64\_t k)

{

```
 as_integer key;

 as_val * v = as_util_hook(get, NULL, m, (as_val *) as_integer_init(&key, k));

 as_integer * i = as_integer_fromval(v);

 return i ? as_integer_toint(i) : 0;

```

}

The added helper functions are good. Alternatively, using existing API:

```
// Setting an integer
as_map_set(m, (as_val *) as_integer_new(1), (as_val *) as_integer_new(10000));

// Getting an integer
as_integer_init(&key, 1);
as_integer_get((as_integer *)as_map_get(m, (as_val *)&key)));

```

Do I assume correctly that if this example is used as-is, it would result in memory leak, since as\_integer\_new allocates an as\_integer on heap, and it must be then freed with as\_integer\_destroy, which is missing from this example? And if so, it would also mean that in order to be able to call as\_integer\_destroy, you HAVE to store the as\_integer (or a pointer to it) in some variable (like the “key” above). Is this correct?

as\_hashmap takes ownership of keys/values and destroys them when the entry is removed. There will be no memory leak if the hashmap itself is eventually destroyed.
