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