New Extent Allocation of Segments

I want a method of determining when a segment such as a data table is about to acquire a new extent because all existing extents are almost full. This method should ideally involve querying the dictionary or executing an Oracle-provided package, and could for example identify the remaining number of average-sized records that can be inserted into the table before another extent will be required.
