222  call = event_funcgraph_exit
224  buffer = buffer
227  event = trace_buffer_lock_reserve(buffer, TRACE_GRAPH_RET, size of entry , flags, pc)
229  If Not event Then Return
231  entry = g_buffer_event_data - return the data of the event*@event: the event to get the data from
232  ret = trace
233  If Not call_filter_check_discard(call, entry, buffer, event) Then Similar to trace_buffer_unlock_commit_regs() but do not dump stack.
