多线程两个功能使用openMP

我在多线程和使用OpenMP方面绝对是新手。但我正在尝试开发一个具有两个功能的程序。

function1(){
get the data from the camera and save it into memory for 1000fps
}
functio2(){
display and refresh the screen each 100ms
}

我认为OpenMP应该是这样的

#pragma omp sections
 {
   { function1(); }
   #pragma omp section
   { function2(); }
 }

，但我不知道我怎么能在代码中实际实现这一点(c++)?如果有人知道，请告诉我。我已经结束了下面的代码，但现在我想让第二部分睡眠每100ms，我怎么做呢?

lastPicNr = 0;  
            if(Fg_AcquireEx(fg,nCamPort,GRAB_INFINITE,ACQ_STANDARD,_memoryAllc)<0){
                CExceptionHandler::GrabberErrorMessage(fg,"Can not start Acquiring images .");  
            }else{
                //Declaring a parallel region that will be broken down into disctinct parallel sections
                #pragma omp parallel sections
                {
                    #pragma omp section
                    {
                        while((lastPicNr = Fg_getLastPicNumberBlockingEx(fg,lastPicNr+1,nCamPort,10,_memoryAllc))<= MaxPics){   
                            iPtr=(unsigned char*)Fg_getImagePtrEx(fg,lastPicNr,0,_memoryAllc);      
                            _PointVector.push_back(iPtr);
                            _lastPicNumber.push_back(lastPicNr);                                
                        }
                    }
                    #pragma omp section
                    {
                        cv::Mat _matrixImage(cv::Size(w,h), CV_8UC1,iPtr , cv::Mat::AUTO_STEP);                                                                 
                        cv::imshow("test",_matrixImage);
                        cv::waitKey(10);
                    }
                }
                PauseClickMode(hDlg);
            }
