Golang GetsockoptByte Examples

Example #1

File: sockopt_bsd.go Project: Bobberino/musings

func ipv4MulticastLoopback(fd int) (bool, error) {
	v, err := syscall.GetsockoptByte(fd, syscall.IPPROTO_IP, syscall.IP_MULTICAST_LOOP)
	if err != nil {
		return false, os.NewSyscallError("getsockopt", err)
	}
	return v == 1, nil
}

Example #2

File: sockopt_bsd.go Project: Bobberino/musings

func ipv4MulticastTTL(fd int) (int, error) {
	v, err := syscall.GetsockoptByte(fd, syscall.IPPROTO_IP, syscall.IP_MULTICAST_TTL)
	if err != nil {
		return 0, os.NewSyscallError("getsockopt", err)
	}
	return int(v), nil
}

Example #3

File: sockopt_bsd.go Project: Christopheraburns/clive

	v, err := syscall.GetsockoptByte(fd, ianaProtocolIP, sysSockoptMulticastLoopback)
	if err != nil {
		return false, os.NewSyscallError("getsockopt", err)
	}
	return v == 1, nil
}

Example #4

File: sockopt_bsd.go Project: Christopheraburns/clive

	if err != nil {
		return 0, os.NewSyscallError("getsockopt", err)
	}

	}
	return int(v), nil
}
