.SH "DESCRIPTION"
.PP
This function allocates and pre\-fills an skb for an event on the testmode multicast group\&.
.PP
The returned skb is set up in the same way as with
\fBcfg80211_testmode_alloc_reply_skb\fR
but prepared for an event\&. As there, you should simply add data to it that will then end up in the
\fBNL80211_ATTR_TESTDATA\fR
attribute\&. Again, you must not modify the skb in any other way\&.
.PP
When done filling the skb, call
\fBcfg80211_testmode_event\fR
with the skb to send the event\&.
.SH "RETURN"
.PP
An allocated and pre\-filled skb\&.
\fBNULL\fR
if any errors happen\&.
