fork() in C – GeeksforGeeks
Fork system call is used for creating a new process, which is called child process, which runs concurrently with the process that makes the fork() call (parent process). After a new child process is created, both processes will execute the next instruction following the fork() system call. A child process uses the same pc(program counter), same CPU registers, same open files which use in the parent process.

c – What Happens When I Call fork() in Unix? – Stack Overflow
Usually when a child dies, the SIGCHLD signal is sent out to the parent which would ideally result in a handler being called subsequent to which the wait() call is executed in that handler. In case the Parent exits without cleaning up the already running or zombie child (via the wait() waitpid calls), the init() process (PID 1) becomes the parent to these now orphan children.

fork (system call) – Wikipedia
When a process calls fork, it is deemed the parent process and the newly created process is its child. After the fork, both processes not only run the same program, but they resume execution as though both had called the system call. They can then inspect the call’s return value to determine their status, child or parent, and act accordingly.

After fork(), where does the child begin its execution?
I thought that fork() creates a same process, so I initially that that in that program, the fork() call would be recursively called forever. I guess that new process created from fork() starts after the fork() call? If I add the following code, to differentiate between a parent and child process,

The fork() system call | HackerEarth
In Linux what fork() does is that it implements the clone() system call, this call takes a series of flags that determine which resources, if any, must be shared between the parent and the child. The clone() system call in turn calls the do_fork(). The do_fork() is defined in kernel/fork.c, line 1566 as of kernel 3.13. The do_fork() does the work of process creation in a synchronized state. The do_fork() now calls copy_process() function.

It takes no arguments and returns a process ID. The purpose of fork() is to create a new process, which becomes the child process of the caller. After a new child process is created, both processes will execute the next instruction following the fork() system call. How many child process will be created with 2 fork calls? Hear this out loudPauseFork #2 is executed by two processes, creating two processes, for a total of four. What happens when you fork a process in program 2?

1) waitpid (): suspends execution of current process until a child as specified by pid arguments has exited or until a signal is delivered. 2) wait3 (): Suspends execution of current process until a child has exited or until signal is delivered. 3) wait4 (): As same as wait3 () but includes pid_t pid value.

Answer (1 of 6): fork() is a system call used to create a new process. The new process is called a child process and the original process is called the parent process. The child process by default is a duplicate of the parent process. By duplicate we mean that the child process has the same code …

What happens if you call fork twice? – Profound-Information
To create a new process, in UNIX, the fork() system call is used. The fork() call is unusual in that it returns twice: It returns in both the process calling fork() and in the newly created process. The child process returns zero and the parent process returns a number greater then zero. What’s an accurate statement regarding a process fork?
