NAME
       pause - wait for signal


SYNOPSIS
       #include <unistd.h>

       int pause(void);


DESCRIPTION
       The pause() library function 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.


RETURN VALUE
       The  pause()  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.


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