• If the exit of a process causes a process group to become orphaned, and if any member of
the newly orphaned process group is stopped, then a SIGHUP signal followed by a
SIGCONT signal is sent to each member of the orphaned process group.
• Locks set by the fcntl( ) function are removed.
Use From the Guardian Environment
The _exit() function can be called from any Guardian process as well as from OSS processes.
Guardian processes, however, have no OSS process ID (PID) and therefore have no wait con-
siderations.
