The point of the '_s' interfaces is having versions that don't have common security holes like buffer overruns, so when it says 'fit within' or 'too big' to me the intent is the implementations >>shall do what's necessary, documented or not<< to prevent those overruns. It seems there it's left open 'how' to work that magic so imps, at their discretion, can use their existing code to get it done or new methods. Either way could reference the same data in the memory manager free(void *) has to, to get the value used with malloc() or realloc(), or calculate a usable size if block chaining/coalescing used. This applies whether the malloc() calls happen at runtime or when creating object descriptions for an object file at compile time, for auto or static declarations. On POSIX systems there's the complexity of supporting dl_sym() too, in some fashion, for externs exported by libraries, but code exists for that also. The vague aspect I see is whether the sizes are 'as declared' or 'as allocated to satisfy alignment practices', not that sizing involves any magic.
