So effectively you are saying, that sendfile() is just a pure send(),
but with diferent arguments? I.e. it is not supposed to send the whole
data it points to, but as much as possible according to send() standard?
Well, it may be a right or wrong decision, and in my opinion sendfile()
is very diferent than send() since it should require the whole data to
be sent, i.e. being like a loop of send()s, but since sendfile() is
effectively a very new approach, it could have different behaviour
rules.
Because of this, Johann, this patch will not be applied, but thanks a
lot for your work, we made a clear meaning on interface usage.
