[Mono-list] Socket.Poll only works after first read of data?

Hi all,

I'm playing with Npgsql to implement CommandTimeout feature.

My idea is to use Socket.Poll method in order to do that.

After adding the infrastructure code to Npgsql, I faced an strange
problem, or maybe it is not strange, just my knowledge about it is :)


After I connect to a socket server, write some data and expect to
receive data, if I call Socket.Poll, it doesn't return true :( I passed
a timeout of 20 seconds: 1000000 * 20 with a SelectMode.Read

If I call socket.Read it works. The strange part of all this is that
after subsequent data exchange with server, Socket.Poll works like a
charm and doesn't timeout anymore.


Is this the way it should be working, or am I missing something?


I tried to put some Thread.Sleep() before calling Poll just to be sure
that it would not be a matter of the server is really taking to much
time to write data, but even with that, it didn't work :( I know it is
useless as on Poll call, I already add a 20 secs wait time.

Any clues?

Thanks in advance.
