## 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.
