export c callback fun:

alias void function(int id) ConnectedCallBack;
alias void function(int id, void* data, int len) ReadCallBack;

export extern (C) void AddListenersss( ConnectedCallBack connectedCallBack=null, ReadCallBack readCallBack=null )
{
    int id = 0;
    int len = 0;
    version(Windows)
    {
        while(true)
        {
            Thread.sleep( dur!("seconds")( 2 ) );
            id++;
            connectedCallBack(id);

            len+=id;
            Thread.sleep( dur!("seconds")( 1 ) );
            readCallBack(id, null, len);
        }
    }
    else
    {
        //server = new epoll();
    }
}

And then use the exported dll called D and C, C #
In addition to the D outside the
Other returns are wrong values​​, such as C #:

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate void OnConnectedCallBack(int id);

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate void OnReceivedCallBack(int sock, IntPtr pData, int len);

[DllImport("ShuNetTcp.dll",EntryPoint = "AddListenersss", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
public static extern void AddListenersss(OnConnectedCallBack connectedCallback, OnReceivedCallBack readCallBack );

using：
m_onConnected = new NetServer.OnConnectedCallBack(OnConnected);
m_onReceived = new NetServer.OnReceivedCallBack(OnRead);
NetServer.AddListenersss( m_onConnected, m_onReceived );

call fun：
private void OnConnected(int id)
{
    Console.WriteLine ("连接完成 Id=>" + id.ToString());
}

private void OnRead(int id, IntPtr pdata, int len)
{
}

Received id and len are wrong! :(
Gurus to help me！！！！！！！！！！！！

O God, no one answered...

add extern(C) to be safe

Thank, Trass3r! Finally correct, why have to export these two?

You specified the C calling convention with UnmanagedFunctionPointer(CallingConvention.Cdecl), and extern(C) means use the C calling convention. Otherwise they'll be expecting a function using the D calling convention, which is incompatible.

The original so thank you
