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 func­
       tion.


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  func­
              tion returned.
