PAUSE(3)                NetBSD Library Functions Manual               PAUSE(3)


NAME

     pause -- stop until signal


LIBRARY

     Standard C Library (libc, -lc)


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 always returns:

     [EINTR]            The call was interrupted.


SEE ALSO

     kill(2), poll(2), select(2), setitimer(2), sigsuspend(2)


STANDARDS

     The pause() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
