Is file<<"Some string"<<endl is an atomic operation.

Is file<<"Some string"<<endl is an atomic operation.
where file is an ofstream object.

If we output a string in ofstream and we provide endl after that,Can we
make sure the whole string will be put in file at a time or the string
can appear in parts.String lenfth is no more than 50 chars.

I have 2 processes on different solaris boxes (NFS) running in
parallel.one process writing lines to the file and other process
reading lines from the file. Can we make sure filestream and endl that
reading process will never get half entry. Either it will get full
entry or no entry. or Do I need to use File Locking?

Hi, I am trying to compile these set of C++ files and trying out class inheritence and function pointers. Can anybody shed some light why my compiler is not compiling them and where I am going wrong? I am using g++ (GCC) 3.3.5 on a Debian Sarge system. The compiler complains: //**************************** //**************************** Compiler output starts *********** cd /home/red/tmp/testprogs/

Hello, I want to create my own index of websites based on my criteria rather than big G's. For example, I might like to index websites according to what they have in their "author" Meta tag ( and rejecting any site that doesn't have one). I will use this idea as a working example. Here is my suggested methodology and I would like some input on problem areas, how to make it better, etc.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents.
