> sigwait is a POSIX extension to ISO C. I believe it's only advantage

  The advantage of sigwait() over sigsuspend() is that the function returns which signals actually were delivered (and removes them from the delivery queue). Sigsuspend() simply returns whenever some signal was delivered, but there's no way of finding out which (except to register signal handlers and set global variables).

  I could be misusing the functions, but I could not find a way of using a sigsuspend() (and sigpending() or any combination of sigprocmasks) that would tell me which signal was delivered that caused sigsuspend() to continue.
