Job control and session management

An overview of Job Control is provided here for completeness and because it interacts with the STREAMS-based terminal subsystem. This section describes how to use a Stream as a controlling terminal. More information on Job Control can be obtained from the following manual pages: exit(2), getpid(2), getsid(2), kill(2), setpgid(2), setpgrp(2), setsid(2),
sigaction(2), signal(2), sigsend(2), termios(3C), waitid(2), waitpid(2), signal(5), and termio(7).
