Again, from the manpage:
[EMSGSIZE] The socket requires that message be sent atomically, and
the size of the message to be sent made this impossible.
From reading this, you can safely imply that it is possible that part of
a message can be sent, unless a socket is specically created to force
all messages to be sent atomically.
