This interface is made obsolete by sigsuspend(2). Sigpause 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
The sigpause function call appeared in BSD 4.3 and has been deprecated. sigsuspend(2), kill(2), sigaction(2), sigprocmask(2), sigblock(2), sigvec(2)
