NAME    [Toc]    [Back]

     sigpause - atomically release blocked signals and  wait  for
interrupt

SYNOPSIS    [Toc]    [Back]

     #include <signal.h>

     int
     sigpause(int sigmask);

DESCRIPTION    [Toc]    [Back]

     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
