86 * SA_ONSTACK indicates that a registered stack_t will be used.
87 * SA_RESTART flag to get restarting signals (which were the default long ago)
88 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
89 * SA_RESETHAND clears the handler when the signal is delivered.
90 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
91 * SA_NODEFER prevents the current signal from being masked in the handler.
93 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
94 * Unix names RESETHAND and NODEFER respectively.
