Developing a custom module

[Ruslan R . Laishev]

Hi There!

 

I developing a my own custom module to be used in the GRUB2 ...

This module is use UDP to talk with a remote server.

So I have checked grub-core/net and try to use a next initialization sequence :

 

...

    /**/

    if ( status = grub_net_resolve_address("172.16.1.1", &kdepo_ip) )

        return    grub_error(grub_errno, "grub_net_resolve_address() -> %d, errno = %d", status, grub_errno);

 

    /* Create UDP's context */

    if ( !(nctx.sd = grub_net_udp_open (kdepo_ip, 512, hook_recv, &nctx)) )

        return    grub_error(grub_errno, "grub_net_udp_open(), errno = %d", grub_errno);

...

 

Test run show me

grub_net_udp_open(), errno = 34

 

Is there some steps I'm need to performs additionaly to get access to netwrok stuff ?
