About A struct Dll Callbacks

[NewCommer]

Hello friends,
I'm writing a code about DllCall a websocket.dll, its documentation looks like this:

Quote

void WebsocketOpen(const WebsocketCallbacks* callbacks, void* param)
This callback is triggered when a WebSocket is established. WebsocketCallbacks is defined as:

typedef void* WebSocketChannel;

typedef struct _WebsocketCallbacks {
    void (CALL_TYPE* OnWillConnect)(void* param, WebSocketChannel channel, const utf8* url);
    bool (CALL_TYPE* OnConnected)(void* param, WebSocketChannel channel);
    void (CALL_TYPE* OnReceive)(void* param, WebSocketChannel channel, int opCode, const char* buf, size_t len);
    void (CALL_TYPE* OnSend)(void* param, WebSocketChannel channel, int opCode, const char* buf, size_t len);
    void (CALL_TYPE* OnError)(void* param, WebSocketChannel channel);
} WebsocketCallbacks;

And I write to AutoIt like this:

Local $pParams = 0
Local $hWsOnWillConnect = DllCallbackRegister(OnWillConnectCallback, 'ptr', 'ptr;ptr;str')
Local $hWsOnConnected = DllCallbackRegister(OnConnectedCallback, 'bool', 'ptr;ptr')
Local $hWsOnReceive = DllCallbackRegister(OnReceiveCallback, 'ptr', 'ptr;ptr;int;ptr;int;bool')
Local $hWsOnSend = DllCallbackRegister(OnSendCallback, 'ptr', 'ptr;ptr;int;ptr;int;bool')
Local $hWsOnError = DllCallbackRegister(OnErrorCallback, 'ptr', 'ptr;ptr')
Local $tCallbackFuncs = DllStructCreate('ptr onWillConnect; ptr onConnected; ptr onReceive; ptr onSend; ptr onError')
$tCallbackFuncs.onWillConnect = DllCallbackGetPtr($hWsOnWillConnect)
$tCallbackFuncs.onConnected = DllCallbackGetPtr($hWsOnConnected)
$tCallbackFuncs.onReceive = DllCallbackGetPtr($hWsOnReceive)
$tCallbackFuncs.onSend = DllCallbackGetPtr($hWsOnSend)
$tCallbackFuncs.onError = DllCallbackGetPtr($hWsOnError)
Local $ret = DllCall('ws.dll', 'ptr', 'WebsocketOpen', 'ptr', DllStructGetPtr($tCallbackFuncs), 'ptr', $pParams)

Func OnWillConnectCallback($pParams, $WsChannel, $sURL)
    #forceref $pParams, $WsChannel, $sURL
    ConsoleWrite(1 & @CRLF)
EndFunc
Func OnConnectedCallback($pParams, $WsChannel)
    #forceref $pParams, $WsChannel
    ConsoleWrite(2 & @CRLF)
EndFunc
Func OnReceiveCallback($pParams, $WsChannel, $opCode, $pBuffer, $LenghtBuffer, $IsContinue)
    #forceref $pParams, $WsChannel, $opCode, $pBuffer, $LenghtBuffer, $IsContinue
    ConsoleWrite(3 & @CRLF)
EndFunc
Func OnSendCallback($pParams, $WsChannel, $opCode, $pBuffer, $LenghtBuffer, $IsContinue)
    #forceref $pParams, $WsChannel, $opCode, $pBuffer, $LenghtBuffer, $IsContinue
    ConsoleWrite(4 & @CRLF)
EndFunc
Func OnErrorCallback($pParams, $WsChannel)
    #forceref $pParams, $WsChannel
    ConsoleWrite(5 & @CRLF)
EndFunc

Can I ask if what I wrote above is correct or not?
Because I ran script and it only printed to console number 1 (means only ran the OnWillConnectCallback function)

Thank you for reading my question. (Sorry my english is not very good)

Your program is going to exit right after your DllCall().

You’re lucky to have gotten even the first Callback before it terminated. 

Add a sleep loop after the call:

While Sleep(10)
WEnd

Hi, Where can I see library's Documentation? is a free library?
