DESCRIPTION
- TIOCGPGRP
- When successful, equivalent to *argp = tcgetpgrp(fd).
- Get the process group ID of the foreground process group on this terminal.
- TIOCSPGRP
- Equivalent to tcsetpgrp(fd, *argp).
- Set the foreground process group ID of this terminal.
- TIOCGSID
- When successful, equivalent to *argp = tcgetsid(fd).
- Get the session ID of the given terminal. This fails with the error ENOTTY if the terminal is not a master pseudoterminal and not our controlling terminal. Strange.
