Yep, that also will work.

What's the optimal approach for Fabian depends on the problem at hand.

My tendency is to use a const, where the const would be implemented in terms
of the sizeof the buf in the context of a null pointer:

const size_t kBufSize = sizeof(((foo*)NULL)->buf);

Or, alternatively (when an option), go the other direction:

const size_t kBufSize = BUFFER_SIZE - HEADER_SIZE;
struct foo
{
  char buf[kBufSize];
};

If a private: scoping is thrown into the mix, then that changes the game
plan.  Hopefully in such a scenario all access is internal to the class
(nicely encapsulated), so the code that needs to sniff these things has
visible access to them.

Sincerely,
