I'm aware of this legacy java.net.Socket specification. I've
asked the person working on Java networking. The New I/O Java
API's is vague on the exact behavior. Since Java networking is
technically above the socket API, so "theoretically" it can
change the meaning of SO_LINGER option. Hence I specifically
asked about *Solaris* apps using the option directly.
*See Also:*
Solaris: setsockopt(3SOCKET)
The SO_LINGER option controls the action taken when unsent
messages are queued on a socket and a close(2) is performed.
If the socket promises reliable delivery of data and
SO_LINGER is set, the system will block the thread on the
close() attempt until it is able to transmit the data *or
until it decides it is unable to deliver the information (a
timeout period, termed the linger interval, is specified in
the setsockopt() call when SO_LINGER is requested)*. If
SO_LINGER is disabled and a close() is issued, the system
will process the close() in a manner that allows the thread
to continue as quickly as possible.
If you read the above carefully, I don't think it actually
specifies that the underlying connection is reset. It is
vague, hence my question.
