79 * SA_ONSTACK indicates that a registered stack_t will be used.
80 * SA_INTERRUPT is a no-op, but left due to historical reasons. Use the
81 * SA_RESTART flag to get restarting signals (which were the default long ago)
82 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
83 * SA_RESETHAND clears the handler when the signal is delivered.
84 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
85 * SA_NODEFER prevents the current signal from being masked in the handler.
86 *
87 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
88 * Unix names RESETHAND and NODEFER respectively.
