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.
