SIGPAUSE(2)                                                        SIGPAUSE(2)


NAME
       sigpause - atomically release blocked signals and wait for interrupt

SYNOPSIS
       sigpause(sigmask)
       int sigmask;

DESCRIPTION
       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 now to
       be blocked.  Sigpause always terminates by being interrupted, returning
       -1 with errno set to EINTR.

       In  normal  usage,  a  signal  is blocked using sigblock(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 sigpause with the  mask  returned
       by sigblock.
