I followed the first implementation like the station dump in wireless [0]. (Some example to print a list over netlink) Now I detect that they use "-ENOENT" for the last entry which should be better than "1". Nevertheless I think this is only good for dynamic changeable list like the use case for [0]. It's very unlikely that the capabilities changes while using of the stack. - Alex [0] http://lxr.free-electrons.com/source/net/wireless/nl80211.c#L3876 -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
