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.
