I actually replaced n by off. Did you mean "don't replace n by off"?
Because the two are identical after the recv error checking. I don't
see the point of maintaining two variables when one suffices. Either n
or off can describe the number of bytes in buf. off is static and
persists across chunks, while n is temporary.
So to clarify, do you want to keep both?
