Consider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? O it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct O None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child terminates. O All of the above. None of the above.
