c - Fork and waiting for the childs outside the pid check -

-

I want to make two parallel forks and wait for them to end. 

 for  (int i = 0; i & lt; 2; i ++) {pid_t pid = fork (); If (pid & lt; 0) {fprintf (stderr, "can not fork!"); Exhaust (EXIT_FAILURE); } Else if (pid == 0) {switch (i) {case 0: // First exhaust exhaust (EXIT_SUCCESS); break; Case 1: // Another child exhaust (EXIT_SUCCESS); break; } break; } Else {// parent}} The problem is that the main program ends before the child, if I add wait (0) to the part of the other parent, then every process , So that they do not work at the same time one by one. I think I can just wait () or waitpid () after the loop, but he is not working either. I thought that after the fork, the parent continues normally, why not wait When is the loop out and if-and structure?  
 Sorry for the upset and thanks in advance.  
  
 
 
 If you add  wait (NULL)  inside the other original part Parents  
 If you add  wait (NULL)  after the loop, the parent process will wait   
 if you want That all children have the same processes running at the same time, then you will need a second loop, where the basics will be  every  to collect the extraction status of the hair process It is important to use  wait () .  
 In your case, there are 2 children - Processes, so 2  wait ()  The system call is enough to add the loop will be like this (I have the  printf  So that you can see it on your  stdout :  
 for  (I = 0; i  ++) {Wait (tap); Printf ("My child has not died% d. \", I); }

c++ - ERROR: cannot open source file x11\xlib.h -

-
I am using OpenCV 2.4.8 and Visual Studio Express 2012. I have included all environmental variables PATH and additional libraries etc. I get this error when I run the code: Error: source file x11 \ xlib.h p> Can not open I tried in Google but I can not be able to get the proper solution. #include & lt; X11 / Xlib.h & gt; #include & lt; X11 / Xutil.h & gt; You can not just use that code on windows While OpenCV itself is very portable, the code is not clearly above it. Instead of using cv :: imshow (), jujojujo2003 was using the native XWindo call for the pirate.)

c - What are pthread cancelation points used for? -

-
In some cases the respondents say that unless the programmers do not know that they are doing the pthread cancellation points (in many cases) If there are very well, the cancellation points should not be used. My question --- what is the use of pthread cancellation points? [Updated from the comment] Does a cancellation status allow those specific API calls to be canceled? Why not others and others? Does anyone want to use them for something else? Is he a hack to deal with a problem in the kernel, or are they contained in some things that are with posics? Do you want to use the user-level code or only the cancellation point in the API? whether a cancellation point allows to cancel those special API calls is? Stuck with PTHREAD_CANCEL_DEFERRED, this can be the center of confusion. You are thinking about it at the rear side about the Allow system call (the API does not name your name) to cancel the cancellation point, checks the call whether a cancellation reque

c# - Show a huge number of data in DevExpress GridView -

-
With 3000 lines I have a DevExpress grid view and each row has 10 as extensions (this means that when I have 30000 loads in grid load items to load) All data loads It takes a long time to do so, then there is a way to show example 100 lines, and when I use the automatic filter, do I show the lines I want? Example I tried to leave and take (using LINQ), but what I actually see for it Also want to use the automatic filter of the grid. Public Static Binding List & lt; Patient & gt; GetObjectUsingLinq (string sql = "", int skipCount = 0, int lekton = 0) {var gsData = GetDataContext (); Var query = (to choose q.nom q with GS dataApotate order); Return new compulsory list & lt; Patient & gt; (LinqHelper.DoSortPaginate (Query, "" Leave, Techcount) .Oolist ()); } and to call it on the grid listPatient = patients.getObjectUsingLinq (); myGrid.DataSource = listPatient; If you need to display large amounts of records in the grid control,
