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(S), getpid(S), getsid(S), kill(S), setpgid(S), setpgrp(S), setsid(S),
sigaction(S), signal(S), sigsend(S), termios(S), waitid(S), waitpid(S), signal(M), and termio(M).
