causes the calling process (or thread) to sleep
until a signal is delivered that either terminates the process or causes
the invocation of a signal-catching function.

only returns when a signal was caught and the
signal-catching function returned.
In this case
pause()
returns -1, and
errno
is set to
EINTR.

a signal was caught and the signal-catching function returned.
