C's lack of array size info strikes again:

    memcpy(current_wmm_ie, ie->data, ie->len);

where "ie" points to data obtained from the net.

C's lack of arrays strikes again. They are essentially syntactic sugar.

What do you mean by C not having arrays?

I assume they mean that C's support for "arrays" is essentially just C's support for pointer arithmetic plus a mapping of a[b] to *(a+b).

You can even swap it a[b] equivalent to b[a].

shouldn't it be:

* (a + b * sizeof(T))

where T is array elements' type?

That's implied in + on a pointer. uint32_t* + 1 actually adds 4.
