IDA Help: auto_mark_range

Plan to perform an action in the future.
This function will put your request to a special autoanalysis queue.
Later IDA will retrieve the request from the queue and process
it. There are several autoanalysis queue types. IDA will process all
queries from the first queue and then switch to the second queue, etc.
