creating child process in c++

[Aqueel]

Hello I want to ask how can i create a child process in Win32 as we do in linux with the help of fork(). Thank you. We Believe in Excellence

I am not going to give you an answer, because you did no give an explanation of what fork() does. You have received a couple of answers about generating a child process. What do you want to know precisely? INTP Every thing is relative...

I'm not a linux expert but I think fork() creates a new thread and not a new process. Am I right (not sure at all about that). The previous answers you get was how to create a process (so run another executable). If you want to run a thread in parallel, then you have to look for CreateThread[^]

Here is the discription of fork() function. "fork creates a child process that differs from the parent process only in its PID and PPID, and in the fact that resource utilizations are set to 0." I wanted to do the same thing in win32. I do not want operating system to allocate saperate resourses to new process. Infact i want the process to share the same resourses that it's parent is using. Are you getting my point? Thank you. We Believe in Excellence

There is no fork equivalent under Windows. I suggest you consider using threads rather than processes - that is the Windows way of handling concurrency.

fork() creates a new process - an exact duplicate of the current process, including the current code location. You can do this:

switch(fork())
{
case 0:
// child process comes here
exit(0);
default:
// parent process comes here
break;
}

Look at CreateThread(). It's exactly what you're after. But read up on multithreading, because you obviously don't know a lot about it. It can be quite tricky to learn...

Actually, its becoming more and more the Linux way of concurrency. NPTL is a stable working thread implementation.
