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.
73  *

75  * Unix names RESETHAND and NODEFER respectively.
