SIGPAUSE(2) BSD System Calls Manual SIGPAUSE(2)NAMEsigpause — atomically release blocked signals and wait for interrupt
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 4.2BSD and has been deprecated.
