By default, TCP connections wait a small fixed interval before
actually sending data, in order to permit small packets to be
combined. This algorithm is named after its inventor, John Nagle, and
is often referred to as 'Nagling'. While this reduces network resource utilization in these
situations, it imposes a delay on all outgoing message data, which can
cause problems in client/server situations.
This function allows this feature to be disabled (de-Nagling,
value=TRUE
) or enabled (Nagling, value=FALSE
) for the
specified socket.
