PAUSE(3)                  OpenBSD Programmer's Manual                 PAUSE(3)

NAME
     pause - stop until signal



SYNOPSIS
     #include <unistd.h>

     int
     pause(void);

DESCRIPTION
     Pause is made obsolete by sigsuspend(2).

     The pause() function forces a process to pause until a signal is received
     from either the kill(2) function or an interval timer (see setitimer(2)).


     Upon termination of a signal handler started during a pause(), the
     pause() call will return.

RETURN VALUES
     Always returns -1.

ERRORS
     The pause() function may set the global variable errno to the following
     error:

     [EINTR]       The call was interrupted.

SEE ALSO
     kill(2),  select(2),  setitimer(2),  sigsuspend(2)

HISTORY
     A pause() syscall appeared in Version 6 AT&T UNIX.
