     #include <signal.h>
     struct sigaction {
             void     (*sa_handler)(int);
             sigset_t sa_mask;
             int      sa_flags;
     };

     int
     sigaction(int sig, const struct sigaction *act, struct sigaction
*oact);

That's from the NetBSD 1.6.2 man page for sigaction(2).  

A few months ago, I bumped into this while making the Firebird database
compile on NetBSD.  IIRC, 1.6.2 signal handling is not POSIX compliant
(it's pre-POSIX), while AIUI the 2.0 release, now in beta, will be.
