You can do what you want by using a stream device that is a string 
(string stream) or a memory
buffer (queue stream) -- these are (pseudo-)I/O devices that you can 
specify when you open
the stream. Here is an example with  string streams:

[eclipse 8]: open(string(""), write, S),
                printf(S, "Hello there %d", [1]),
        get_stream_info(S, name, String), close(S).


S = 7
String = "Hello there 1"

The `trick' here is the `name' of the stream is irs content - hence the 
use of get_stream_info/3.

Cheers,
