SIGPAUSE(3)             NetBSD Library Functions Manual            SIGPAUSE(3)


NAME

     sigpause -- atomically release blocked signals and wait for interrupt


LIBRARY

     Standard C Library (libc, -lc)


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.
