pause - stop until signal
Standard C Library (libc, -lc)
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.
Always returns -1.
The pause() function always returns:
[EINTR] The call was interrupted.
kill(2), poll(2), select(2), setitimer(2), sigsuspend(2)
The pause() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
A pause() syscall appeared in Version 6 AT&T UNIX.
