CFG80211_TESTMODE_AL(9)                     Test mode                     CFG80211_TESTMODE_AL(9)



NAME
       cfg80211_testmode_alloc_event_skb - allocate testmode event

SYNOPSIS
       struct sk_buff * cfg80211_testmode_alloc_event_skb(struct wiphy * wiphy, int approxlen,
                                                          gfp_t gfp);

ARGUMENTS
       wiphy
           the wiphy

       approxlen
           an upper bound of the length of the data that will be put into the skb

       gfp
           allocation flags

DESCRIPTION
       This function allocates and pre-fills an skb for an event on the testmode multicast group.

       The returned skb is set up in the same way as with cfg80211_testmode_alloc_reply_skb but
       prepared for an event. As there, you should simply add data to it that will then end up in
       the NL80211_ATTR_TESTDATA attribute. Again, you must not modify the skb in any other way.

       When done filling the skb, call cfg80211_testmode_event with the skb to send the event.

RETURN
       An allocated and pre-filled skb.  NULL if any errors happen.
