wait

I have executed a block of code. And it is as shown below: #include<stdio.h> main() { int i=0; fork(); printf("The value of i is:%d\n",++i); fork(); printf("The value of j is:%d\n",++i); fork(); wait(); } And I got following output: The value of i is:1 The value of j is:2 The value of i is:1 The value of j is:2 The value of j is:2 pckoders@ubuntu:~$ The value of j is:2 Can anyone explain to me what role fork() and wait() functions play here? The program generates a tree of processes. At every fork , this tree branches in two. If you grab a piece of paper, it's not very hard to draw this tree;

I have a test script in Robot Framework which I want to reduce its elapsed time. I have below command as a part of the test procedure: wait until element is enabled id=${elementId} In run time, it takes about 5 seconds to be done; I've set selenium implicit wait to 2 seconds using below line at the beginning of the test: set selenium implicit wait 2 seconds I get the applied selenium implicit wait afterwards with get selenium implicit wait and it returns 2 seconds , but the first command still takes about 5 seconds to complete. What should I do to reduce this time?? Any help or suggestion will

How can i block UI from all interactions for some seconds by user in Android? I would like to know, how to do this with some delay timing like wait(5000); You can override dispatchTouchEvent and stop the call to super.dispatchTouchEvent(ev); Any touch event will have to go through this method before it is handled. Set a boolean that you control and use it in the method to determine whether you wish to block control. private boolean stopUserInteractions = false; public boolean dispatchTouchEvent(MotionEvent ev) { if (stopUserInteractions) { return true; } else { return super.dispatchTouchEvent

I need to get information from the server on the client side. So on the server side I got this when a client first connect: socket.on('adduser', function(username){ // misc code, where i set num_player and whatnot socket.emit('confirmauth', socket.id, socket.num_player, function(data){ console.log(data) }); // code } and on the client side I got this: var current_player; socket.on('confirmauth', function(id, username, num, callback) { current_player = new Player(username,id, num); console.log(current_player.id); // works console.log(current_player.num); //works callback('ok i got it'); });

I am trying to make a program that suspends its execution until a signal arrives . Then, after the signal arrives I just want my code to continue its execution from where it was . I don't want it to execute a function handler or whatsoever. Is there a simple way of doing this? I have been struggling for a week or so, reading here and there, and didn't manage to get a fully operative code. In particular, I want the main program to create a thread that waits for some particular event to happen (e.g., a user has input some data to stdin). Meanwhile, the main program is doing something but at some

I am running script to unrar some files and the remove the rar files afterwards. I am doing this by running the command through shell. I have tried several different ways to make the script wait until it's done unpacking the files, but it still goes ahead and deletes the file before they are done being used. I have tried the code below, which is a no go. I have tried to see if i could get the wait() to work, but also no luck. Any ideas? running python 2.7 EDIT: I want the script to run the command :) p = subprocess.Popen('unrar e ' + root + '/' + i + ' ' + testfolder, bufsize=2048, shell=True,

I have a set of code that contains: Application.Wait (Now + TimeValue("4:00:00")) This is essentially pausing the macro for a four hour window from 3 AM (when it finishs running the code) till 7 AM (when it should resume). The code is on an endless loop essentially. I want the user to be able to have control during that time to edit certain cells. I have tried DoEvents but have not found the way to keep the macro running, yet provide control to the user during that time when the macro is doing nothing but waiting. Any insight would be appreciated. Thanks! EDIT: One more followup question. I

I want to run initializations of some objects asynchronously, but some objects depend on others being initialized. And then all objects need to be initialized before the rest of my application continues. Is it possible to call Wait() on a task and later call Wait() on it again, or as in my example WaitAll() on a collection where it is included? Dictionary<String, Task> taskdict = new Dictionary<String, Task>( ); taskdict.Add( "Task1", Task.Factory.StartNew( ( ) => { //Do stuff } ) ); taskdict.Add( "Task2", Task.Factory.StartNew( ( ) => { taskdict[ "Task1" ].Wait( ); //Do stuff } ) ); try {
