SIGPAUSE(3)               OpenBSD Programmer's Manual              SIGPAUSE(3)

NAME
     sigpause - 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

HISTORY
     The sigpause() function call appeared in 4.2BSD and has been deprecated.
