Re: [PATCH] connect() return value.

Hello!

it returns -EISCONN. This behavior is consistent in all operating
systems which I have tested, which include the following:

This is very strange. Linux should return success once.

Probably, I should explain why I ask this. This is a necessary
element of implementation of restartable connect(). If connect()
is restarted after signal, it should return success on connected
socket sometimes rather than -EISCONN.

On Linux (v 2.4.18):

read() returns 0 with an errno of 115. On Linux 115 corresponds to 
-EINPROGRESS.

I am sorry, this machine is not running Linux.

Zero length read() always returns zero, not depending of socket state.

Yep. Though I would really like it if it conforms to what the rest of 
the Unices does with that behavior.

Non-sense. We are not going to emulate pathological cases.

So, we can agree

Did we argue about this? :-)
