Hi Elias,
if have implemented the *poll() *as a non-default alternative to
*select() *in *APserver*.
Unfortunately I can't reproduce the problems that I had earlier (they
occurred in the middle
of development), but I would be surprised if*poll()* would differ
from*select() *in that respect.
Sorry, not POLLPRI. It's POLLERR or POLLHUP. You can see how it's done here:

Elias

I believe if you use poll() rather than select(), you should be able to
detect this state. Add a listener for the event POLLPRI.

Hi Elias,
given that hardly anybody uses shared variables these days this discussion
is more on the theoretical side than of practical relevance.
For that reason I would like the solution to be as simple as possible.
The extra things needed as you state below make things more complicated

I did not know about that feature. Interesting. Also interesting that it's
not supported on OSX.
That said, I still think Unix domain sockets are good in this case. There
are just a few things that needs to be done in order to make them solid. I
think I did most of those things in the native code
Hi Elias,
the idea is this:
man 7 unix says:
/abstract: an abstract socket address is distinguished by the fact//
// that sun_path[0] is a null byte ('\0'). The socket's
address in//
// this namespace is given by the additional bytes in sun_path
that are//
//
Ah, sorry. My question was about the "+ABSTRACT_OFFSET". That particular
addition of the value 1 to the sun_path field was what caused the failure.
What I wondered was what is the purpose of ABSTRACT_OFFSET?
Regards,
Elias

Hi Elias,
Unix Domain Sockets were your proposal if I remember correctly :-) .
They caused a few extra problems, for example select() does not
notice when a connection is closed.
Not sure which call you mean?

I had never been able to get APserver to work properly, and particularly
not with the Unix Domain Sockets.
But, I finally figured it out. :-)
