64 * SA_NOCLDSTOP flag to turn off SIGCHLD when children stop.
65 * SA_NOCLDWAIT flag on SIGCHLD to inhibit zombies.
66 * SA_SIGINFO deliver the signal with SIGINFO structs
67 * SA_THIRTYTWO delivers the signal in 32-bit mode, even if the task
68 * is running in 26-bit.
69 * SA_ONSTACK allows alternate signal stacks (see sigaltstack(2)).
70 * SA_RESTART flag to get restarting signals (which were the default long ago)
71 * SA_NODEFER prevents the current signal from being masked in the handler.
72 * SA_RESETHAND clears the handler when the signal is delivered.
74 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
75 * Unix names RESETHAND and NODEFER respectively.
