System Calls pause(2)
pause - suspend process until signal
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.
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.
The pause() function will fail if:
EINTR A signal is caught by the calling process and control
is returned from the signal-catching function.
