In that case, is there a solid way to extract that identifier? Or will
I need to do some I'm aware of sprintf calls, is it common practice to
simply "sprintf" the first integer of the received binary data into a
buffer and (effectively) switch-case on that buffer, then memcpy the
remaining data that follows? Or is there a better way of doing this?
Cheers,
Alex

with it's "instanceof" operator. As far as I know this type of
mechanism, or
anything similar, doesn't really exist in C/C++. So my next

we're sending binary data along and receiving it as binary data,
what's the
most efficient way of type-checking the probable struct being piped
through?
You give it a number which designates its type. You'd usually prepend
such a number to each of your messages, so that you know how to
interpret them on the other end.
