72 * SA_ONSTACK indicates that a registered stack_t will be used.
73 * SA_RESTART flag to get restarting signals (which were the default long ago)
74 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
75 * SA_RESETHAND clears the handler when the signal is delivered.
76 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
