An operating system may provide variations of the wait call that allow a process to wait for any of its child processes to exit, or to wait for a single specific child process (identified by its process ID) to exit. Some operating systems issue a signal to the parent process when a child process terminates, notifying the parent process and ...

Such a process becomes the child of a special parent ...
