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.
