SIGPAUSE(2)

NAME
       sigpause - atomically release blocked signals and wait for
       interrupt

SYNOPSIS
       #include <<signal.h>>

       int sigpause(int sigmask);

DESCRIPTION
       This interface is made obsolete by sigsuspend(2).

       sigpause assigns sigmask to the set of masked signals  and
       then  waits  for  a signal to arrive; on return the set of
       masked signals is restored.

       sigmask is usually 0 to indicate that no signals are to be
       blocked.  sigpause always terminates by being interrupted,
       returning -1 with errno set to EINTR.

CONFORMING TO
       4.4BSD.  The sigpause function call appeared in 4.3BSD and
       is deprecated.
