struct sigaction

#ifdef __USE_POSIX199309
    union
      {
        /* Used if SA_SIGINFO is not set.  */
        __sighandler_t sa_handler;
        /* Used if SA_SIGINFO is set.  */
        void (*sa_sigaction) (int, siginfo_t *, void *);
      }
    __sigaction_handler;
# define sa_handler     __sigaction_handler.sa_handler

#else
    __sighandler_t sa_handler;
#endif

    /* Special flags.  */
    unsigned long int sa_flags;

    /* Additional set of signals to be blocked.  */
    __sigset_t sa_mask;
  };

#define SA_SIGINFO    0x00000010  /* Invoke signal-catching function with
                                     three arguments instead of one.  */

and

typedef void (*__sighandler_t) (int);
