函数WlanRegisterNotification不编译 [英] The function WlanRegisterNotification dont compile

问题描述

大家好，

我在Windows XP SP3上使用Visual C ++ 2008 Express Edition，我写了这段代码：
$

Hi all,

I've Visual C++ 2008 Express Edition on Windows XP SP3, and I write this code:

#include <iostream>
#include <string>
#include <windows.h>

// headers needed to use WLAN APIs

#include <wlanapi.h>


// Application defined callback function

VOID NotificationCallback(
    PWLAN_NOTIFICATION_DATA pNotifData, 
    PVOID pContext
    )
{
  std::cout <<" -- NotificationCallback -- " <<std::endl;
  return;
}


int main()
{
  DWORD rtn;
  DWORD dNegotiatedVersion;
  HANDLE hClientHandle;

  dNegotiatedVersion = 0;

  rtn = WlanOpenHandle(
    WLAN_API_VERSION,
    NULL,
    &dNegotiatedVersion,
    &hClientHandle
  );

  if(rtn != ERROR_SUCCESS)
  {
    std::cerr <<"Error occured in WlanOpenHandle" <<std::endl;
    return -1;
  }

  WlanRegisterNotification(
    hClientHandle,
    WLAN_NOTIFICATION_SOURCE_ALL,
    FALSE,
    NotificationCallback,
    NULL,
    NULL,
    NULL
  );

  WlanCloseHandle(hClientHandle, NULL);

  return 0;
} // end of function main

但是当我编译时我有这个错误：

错误C2664： 'WlanRegisterNotification'：无法将参数4从'void（__ cdecl *）（PWLAN_NOTIFICATION_DATA，PVOID）'转换为'WLAN_NOTIFICATION_CALLBACK'

什么错了？任何人都可以帮助我？
Thanx。

But when I compile I have this error:

error C2664: 'WlanRegisterNotification' : cannot convert parameter 4 from 'void (__cdecl*)(PWLAN_NOTIFICATION_DATA,PVOID)' to 'WLAN_NOTIFICATION_CALLBACK'

What's wrong? Anybody can help me?
Thanx.

推荐答案

尝试修改你的原型以包含WINAPI
用于VOID WINAPI NotificationCallback （
PWLAN_NOTIFICATION_DATA pNotifData，
PVOID pContext
）

Try hange your prototype to include WINAPI

VOID WINAPI NotificationCallback(
    PWLAN_NOTIFICATION_DATA pNotifData,
    PVOID pContext
    )
