SIGPAUSE(3) OpenBSD Programmer's Manual SIGPAUSE(3)NAMEsigpause - atomically release blocked signals and wait for interrupt
SYNOPSIS
#include <signal.h>
int
sigpause(int sigmask);
DESCRIPTION
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.
