c - 以下代码将创建多少个进程？

Question

以下代码生成的进程总数是多少？

if(fork() && fork()){
    fork();
}

if(fork() ||fork()){
    fork();
    fork();
}

AND 将充当短路运算符，因此第二个 fork 只会针对父级而不是子级执行。之后如何进行？

Answer 1

We have to validate fork return values. Actually based on return only we can able to check no of process on your program.


fork Return Value :

-1                  => Failure.
0                   => Return value for child process.
Child process id    => Return value for parent process.
