issue about WifiInformationElement::Serialize (buffer::iterator) const

[Le Tian]

Hi all,

I have a question about WifiInformationElement::Serialize (buffer::iterator) const function.

Buffer::Iterator

WifiInformationElement::Serialize (Buffer::Iterator i) const

{

  i.WriteU8 (ElementId ());

  i.WriteU8 (GetInformationFieldSize ());

  SerializeInformationField (i);

  i.Next (GetInformationFieldSize ());

  return i;

}

In my opinion, SerializeInformationField (i) in above definiton already update i, so is it necessary to update i again with i.Next (GetInformationFieldSize ())?

Kind regards

Le

Hi,

yes, it's necessary. SerializeInformationField will update its own private copy of the iterator, and the iterator of the calling function will be unaffected.

Basically, you need this trick (or you'd have to use pointers to iterators).

Have fun,

T.

Hi Tommaso,

I understand, thanks a lot.

Kind regards

Le
