pause - wait for signal
The pause(2) syscall causes the invoking process (or thread) to sleep until a signal is received that either terminates it or causes it to call a signal-catching function.
The pause(2) function only returns when a signal was caught and the signal-catching function returned. In this case pause(2) returns -1, and errno is set to EINTR.
- a signal was caught and the signal-catching function returned.
