ReuseAddress and the Compact framework

[afonso.ricardo]

Hi there.

Can somebody point me to a work around to the anoying CF bug described
in:

http://msdn.microsoft.com/smartclient/understanding/netcf/FAQ/default.aspx#8.11

I've tried P\Invoking setsockopt, however it return a error informing
me that the socket handle was not valid.

Being as the Socket handle was obtained using Socket.Handle, I've run
out of options.

Thank you very much,

Can you post a snippet of the problem code you are using to call setsockopt?

But of course...

This code was inspired by another post in this forum (credit were it's
due). Unfortunately the post didn't answer the question completely

Here it goes:

Invocation (SendSocket is a regular .NET Socket):

this.SetSocketOption(SendSocket.Handle, SocketOptionLevel.Socket,
SocketOptionName.ReuseAddress, 1) ;

(Wrapper function to call setsockopt Interop)
public int SetSocketOption(IntPtr m_Handle,SocketOptionLevel
optionLevel, SocketOptionName optionName, int optionValue)
{

return
setsockopt(
m_Handle,
optionLevel,
optionName,
ref optionValue,
Marshal.SizeOf(optionValue));
}

(setsockopt interop declaration)
[DllImport("Winsock",EntryPoint="setsockopt", CharSet=CharSet.Auto,
SetLastError=true)]
public extern static int setsockopt(IntPtr _sock, SocketOptionLevel
level, SocketOptionName name, ref int optionValue, int int_val);

Here it is...

Thanks in advance for your help.
