pause - wait for signal
#include <unistd.h> int pause(void);
pause() 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.
pause() returns only when a signal was caught and the signal-catching function returned. In this case, pause() returns -1, and errno is set to EINTR.
EINTR a signal was caught and the signal-catching function returned.
