# sigsuspend(2)

    NAME
         sigsuspend - suspend until signalled

    SYNOPSIS
         #include <signal.h>

         int sigsuspend(const sigset_t *set)

    DESCRIPTION
         Sigsuspend() installs the signal mask referenced by set and suspends  the
         process  until  signalled.   The  signal  is  handled, the signal mask is
         restored to the value it  had  before  the  sigsuspend()  call  and  call
         returns.

    SEE ALSO
         pause(2), sigaction(2), sigpending(2), sigprocmask(2), sigset(3).

    DIAGNOSTICS
         Sigsuspend() never returns normally, so it always returns -1.  The  error
         code  is either EINTR indicating that a signal has arrived, or EFAULT for
         a bad set address.
