PAUSE(2) System Calls PAUSE(2)

NAME

pause - suspend process until signal

SYNOPSIS

#include <unistd.h>

int pause(void);

DESCRIPTION

The pause() function suspends the calling process until it receives a
signal. The signal must be one that is not currently set to be
ignored by the calling process.


If the signal causes termination of the calling process, pause() does
not return.


If the signal is caught by the calling process and control is
returned from the signal-catching function (see signal(3C)), the
calling process resumes execution from the point of suspension.

RETURN VALUES

Since pause() suspends thread execution indefinitely unless
interrupted by a signal, there is no successful completion return
value. If interrupted, it returns -1 and sets errno to indicate the
error.

ERRORS

The pause() function will fail if:

EINTR
A signal is caught by the calling process and control is
returned from the signal-catching function.
