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.

NAME

     sigsuspend -- atomically release blocked signals and wait for interrupt

SYNOPSIS

     #include <signal.h>

     int
     sigsuspend(const sigset_t *sigmask);

DESCRIPTION

     Sigsuspend() temporarily changes the blocked signal mask to the set to which sigmask points, and then waits for a signal to arrive; on return
     the previous set of masked signals is restored.  The signal mask set is usually empty to indicate that all signals are to be unblocked for
     the duration of the call.

     In normal usage, a signal is blocked using sigprocmask(2) to begin a critical section, variables modified on the occurrence of the signal are
     examined to determine that there is no work to be done, and the process pauses awaiting work by using sigsuspend() with the previous mask
     returned by sigprocmask.

RETURN VALUES

     The sigsuspend() function always terminates by being interrupted, returning -1 with errno set to EINTR.

SEE ALSO

     sigaction(2), sigprocmask(2), sigsetops(3)

STANDARDS

     The sigsuspend function call conforms to IEEE Std 1003.1-1988 (``POSIX.1'').
