vc DLL中使用回调函数

dll

typedef void(__stdcall *Callback_GetYUV420P)( unsigned char * );
typedef void(__stdcall *Callback_GetH264Stream)( unsigned char * ,int );

Callback_GetYUV420P pfun;
Callback_GetH264Stream pfun2;


int PXIE638_StartCapture( Callback_GetYUV420P fun,Callback_GetH264Stream fun2)
{
	DWORD dwReturn;
	for ( int i=0; i < MAX_DECODER_CAM; i++ )
	{
		m_camera_events[i] = CreateEvent(NULL, FALSE, FALSE, NULL);

	}
//	fp_yuv422 = fopen(yuvfilename,"wb+");
	m_mutex_handle = CreateMutex(NULL, 0, NULL);
	m_camera_event_stop = CreateEvent(NULL, FALSE, FALSE, NULL);
	m_stream_thread_running = TRUE;

	 ULONG address[5];
	 EVENT_HANDLE_PARAM event_param;
	event_param.channelNum = 0;
	event_param.m_hEvent = m_camera_events[0];
    DeviceIoControl(m_dev_handle, IOCTL_START_CAPTURE, &event_param, sizeof(event_param), &address[0], sizeof(address), &dwReturn, NULL);	

	m_pSharedDataBuffer
