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.

HISTORY
A pause() system call first appeared in the Programmer's Workbench (PWB/UNIX) and was then ported to Version 7 AT&T UNIX. It was reimplemented as a wrapper around the sigpause() and sigblock() system calls in 4.2BSD, and around the sigsuspend(2) and sigprocmask(2) system calls in 4.3BSD-Reno.
