sigpause(int sigmask);


() assigns sigmask to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored. sigmask is usually 0 to indicate that no signals are to be blocked. sigpause() always terminates by being interrupted, returning -1 with errno set to EINTR.
