76 * SA_ONSTACK indicates that a registered stack_t will be used.
77 * SA_INTERRUPT is a no-op, but left due to historical reasons. Use the
78 * SA_RESTART flag to get restarting signals (which were the default long ago)
79 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
80 * SA_RESETHAND clears the handler when the signal is delivered.
81 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
82 * SA_NODEFER prevents the current signal from being masked in the handler.
84 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
85 * Unix names RESETHAND and NODEFER respectively.
