You do have that. You must have 12 bytes for any packet. The
last four bytes of that tells you the number of bytes remaining.
I use that in my test server now to detect when I've accumulated

In this structure I need to get the key before I can get the body length
;-) I looked at the original structure now, and you're right :-)
