55 * SA_FLAGS values:
57 * SA_ONSTACK indicates that a registered stack_t will be used.
58 * SA_RESTART flag to get restarting signals (which were the default long ago)
59 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
60 * SA_RESETHAND clears the handler when the signal is delivered.
61 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
62 * SA_NODEFER prevents the current signal from being masked in the handler.
64 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
65 * Unix names RESETHAND and NODEFER respectively.
