Yep, but this one has not the usual layout of struct+pointer (that's the whole point), and I'm not sure it qualifies as "yet another" since it was written in 2006.

It appears to me to be "yet another" because the length before the string approach is usually referred to as a b-string.
windows (for example) has had a comprehensive b-string library (type is called BSTR) for about 20 years - due to it's age and provenance it has the downside of thinking a character is a 16-bit value...

You're right, sorry. I only scanned the document, saw the struct, and closed the tab. The way you use a header before the data is similar to how Ruby represents its strings internally.
