CE获取Wifi的设备名、连接状态和信号强度

#include 
#include 
#include 
 
   
HANDLE hNdis = ::CreateFile( NDISUIO_DEVICE_NAME, GENERIC_ALL, 0, NULL, OPEN_EXISTING,
                             FILE_ATTRIBUTE_NORMAL|FILE_FLAG_OVERLAPPED,
                             (HANDLE)INVALID_HANDLE_VALUE );

三、获取设备名称

UCHAR                  cbQueryBuffer[ 1024 ];
PNDISUIO_QUERY_BINDING pQueryBinding;
DWORD                  dwBytesReturned = 0;

pQueryBinding = (PNDISUIO_QUERY_BINDING)&cbQueryBuffer[ 0 ];
pQueryBinding->BindingIndex = 0;

if ( ::DeviceIoControl( hNdis,
                        IOCTL_NDISUIO_QUERY_BINDING,
                        (LPVOID)&cbQueryBuffer[ 0 ],
                        sizeof(NDISUIO_QUERY_BINDING),
                        (LPVOID)&cbQueryBuffer[ 0 ],
                        sizeof(cbQueryBuffer),
                        &dwBytesReturned,
                        NULL ) == TRUE )
{
    TCHAR* pDeviceName = (TCHAR*)( cbQueryBuffer + pQueryBinding->DeviceNameOffset );
}

 

四、检测连接状态

NIC_STATISTICS nicStatistics = { 0 };
DWORD          dwBytesReturned = 0;
BOOL bConnected = FALSE;

nicStatistics.ptcDeviceName = pDeviceName;

if ( ::DeviceIoControl( hNdis,
                        IOCTL_NDISUIO_NIC_STATISTICS,
                        NULL,
                        0,
                        &nicStatistics,
                        sizeof(NIC_STATISTICS),
                        &dwBytesReturned,
                        NULL ) == TRUE )
{
    bConnected = ( nicStatistics.MediaState == MEDIA_STATE_CONNECTED );
}

五、获取信号强度

NDISUIO_QUERY_OID ndisQueryOid = { 0 };
DWORD             dwBytesReturned = 0;
int nDb = 0;

ndisQueryOid.Oid = OID_802_11_RSSI;
ndisQueryOid.ptcDeviceName = pDeviceName;

if ( ::DeviceIoControl( hNdis,
                        IOCTL_NDISUIO_QUERY_OID_VALUE,
                        (LPVOID)&ndisQueryOid,
                        sizeof(ndisQueryOid),
                        (LPVOID)&ndisQueryOid,
                        sizeof(ndisQueryOid),
                        &dwBytesReturned,
                        NULL ) == TRUE )
{
    ::CopyMemory( &nDb, &ndisQueryOid.Data[ 0 ], sizeof(ULONG) );
}
