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.
