HP-UX Reference (11i v3 07/02) - 2 System Calls (vol 5)

exit(2) exit(2)

• A SIGCHLD signal is sent to the parent process.

• If the calling process is a controlling process, the

SIGHUP signal is sent to each process in the fore-

ground process group of the controlling terminal belonging to the calling process. The controlling ter-

minal associated with the session is disassociated from the session, allowing it to be acquired by a new

controlling process.

• If the exit of the calling process causes a process group to become orphaned, and if any member of the

newly-orphaned process group is stopped, all processes in the newly-orphaned process group are sent

SIGHUP and SIGCONT signals.

• If the current process has any child processes that are being traced, they are sent a

SIGKILL signal.
