Detailed Description

Definition of a Generic Netlink family.

Example:

static struct genl_cmd foo_cmds[] = {
        [...]
};
 
static struct genl_ops my_genl_ops = {
        .o_name                 = "foo",
        .o_hdrsize              = sizeof(struct my_hdr),
        .o_cmds                 = foo_cmds,
        .o_ncmds                = ARRAY_SIZE(foo_cmds),
};
 
if ((err = genl_register_family(&my_genl_ops)) < 0)
