Here is the code I used to emulate the wait3 BSD function on SCO UNIX.
Hope it will fix you right up.

-------------------code fragments follow---------------

register int    childPid;

#if defined(SYSV_UNIX)
while ((childPid = waitpid(NULL, &w, WUNTRACED | WNOHANG)) > 0) {
#else
while ((childPid = wait3(&w, WUNTRACED | WNOHANG,
    (struct rusage *)NULL)) > 0) {
#endif
  if (WIFSTOPPED(w)) {
    fprintf(stderr,"%s: Child %d Stopped.\r\n", ProgramName, childPid);
    }
  else
  if (WIFEXITED(w)) {
    fprintf(stderr,"%s: Child %d Exited.\r\n", ProgramName, childPid);
    }
  else
  if (WIFSIGNALED(w)) {
    fprintf(stderr,"%s: Child %d Killed.\r\n", ProgramName, childPid);
    }
