7-zip's truncated stdout stream

Hello,

I am tinkering with the 7-zip command line tool, feeding the app by StdinWrite(),
and getting its output by StdoutRead().


It uncompresses the data without error on both cases.
The symptom is a truncated list of processed files (the stdout stream).

The problem occurs, when 7-zip is being fed through the stdin stream.
But by normal invoking (filename in the command line), it spits out its stdout stream normally.


So, the big question is: am I missing something very basic, or this is a bug, or software incompatibility, or what?

Thx in advance.
