socket maxconnections?

[Ole]

As a newbie to socket communication I would like to know more about
'SocketOptionName.MaxConnections'. Everywhere I look for examples on using
socket I see the statement:
listenSocket.Listen((int)SocketOptionName.MaxConnections);
used , but the .NET documentation says this about Maxconnections: "Not
supported; will throw a SocketException if used."
What should I do and what is the code line actually doig?

Thanks
Ole

Hello, Ole!

Line above means that listenSocket state will be changed to LISTENING ( it will accept connections via Accept method ). And number of pending connections is equal to SocketOptionName.MaxConnections.

SocketOptionName.MaxConnections has the same value as int.MaxValue has ( 0x7fffffff ).

Exception will be thrown when you will try to set socket option and use MaxConnections as an option name, e.g.
listenSocket.SetSocketOption(..., SocketOptionName.MaxConnections, .... );

Thanks. Still not sure what the number is actually good for: what would
happen if I wrote 1 instread of MaxConnections?

Best regards,

Hello, Ole!

That will mean that number pending connections will be equal to 1.
That is if there are a lot hosts that want to connect connection queue's size will be 1, thus
some hosts will be refused connection.
