- =?UTF-8?B?IuaLlueLl+aVo+atpSI=?= (1/1) Apr 26 2012 O God, no one answered...
- Trass3r (1/4) Apr 26 2012 add extern(C) to be safe
- =?UTF-8?B?IuaLlueLl+aVo+atpSI=?= (2/7) Apr 27 2012 Thank, Trass3r! Finally correct, why have to export these two?
- Matt Peterson (6/14) Apr 27 2012 You specified the C calling convention with
- =?UTF-8?B?IuaLlueLl+aVo+atpSI=?= (2/19) Apr 28 2012 The original so thank you
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(); } } In addition to the D outside the [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!!!!!!!!!!!!

export c callback fun: alias void function(int id) ConnectedCallBack; alias void function(int id, void* data, int len) ReadCallBack;add extern(C) to be safe
