I have no idea what strstream does, so I can't accurately answer your question. 
However, Ada.Text_IO has several nested generic packages that allowing putting 
and getting to and from Strings.

Yes, Text_IO itself... To be more precise, the generic packages (e.g.,
Integer_IO, Modular_IO, ...) contained in Text_IO.  This means that
you will need to specialize them before use.  Check Appendix A.10 of
the beloved RM (Reference Manual) for more informations.

Example:

--- File test.adb ------
with Text_Io;

procedure Test is
   -- Specialize Text_Io.Integer_Io
   package Int_Io is new Text_Io.Integer_Io(Integer);

   Buffer : String(1..5) := (others => 'x');
begin
   Int_Io.Put(Buffer, 42);
   Text_Io.Put_Line("[" & Buffer & "]"); -- will print [   42]
end Test;

I guess you are looking for something like Unbounded_Stream in the
package Zip_Streams:
http://unzip-ada.sourceforge.net/za_html/zip_streams__ads.htm#52_9
(indeed the "Zip" in that package is unhappy, it is a general-purpose
package (stream with name & time))
