求助0xC0000005: 读取位置 0x00000004 时发生访问冲突错误

Question

void DInputClass::GetInput()
{
HRESULT hr = m_KeyboardDevice->GetDeviceState(sizeof(m_keyBuffer), (void**)&m_keyBuffer); //在这里提示错误了
//获取键盘输入消息
if(hr)
{
m_KeyboardDevice->Acquire();

m_KeyboardDevice->GetDeviceState( sizeof(m_keyBuffer),(LPVOID)m_keyBuffer );
}

hr = m_MouseDevice->GetDeviceState(sizeof(DIMOUSESTATE), (void**)&m_MouseState); 
//获取鼠标输入消息
if(hr)
{
    m_MouseDevice->Acquire();
    m_MouseDevice->GetDeviceState( sizeof(DIMOUSESTATE), (void**)&m_MouseState);
}

}
请问出了什么问题？在其他的程序可以跑。。。

m_keyboarddevice估计不是正确的指针，你没有正确获取到。
