Do you have sample code you could share? > Thanks, > Bz yeah... i think i might need some help too. i figured out the kernel side of it from this tutorial: http://linux-net.osdl.org/index.php/Generic_Netlink_HOWTO but i am confused on the user-side of this. i found code for getdelay.c : http://www.mjmwired.net/kernel/Documentation/accounting/getdelays.c which seems to use generic sockets to send the commands, but i still need to figure out how to send data from kernel space to user. one thing i noticed is that the code is using recv() to receive a message, so does that mean i have to expect the message to come? does this function block until a message arrives? - ilya p.s. it would be nice if you had some sample code for both sides. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
