# NAME

pause — stop until signal

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

#include <unistd.h>

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 IEEE Std 1003.1-1990 (“POSIX.1”).

# HISTORY

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