63 * SA_FLAGS values:
65 * SA_ONSTACK is not currently supported, but will allow sigaltstack(2).
66 * SA_RESTART flag to get restarting signals (which were the default long ago)
67 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
68 * SA_RESETHAND clears the handler when the signal is delivered.
69 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
70 * SA_NODEFER prevents the current signal from being masked in the handler.
72 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
73 * Unix names RESETHAND and NODEFER respectively.
