thank you for your answer.<br />
unfortunately, it didn't work. it still gets all buffered and<br />
output after program termination.<br />

I've never seen this before. &nbsp;What platform/compiler?<br />

BTW, I recall that cout is unitbuf by default.<br />

Does &quot;cerr&quot; behave like you want it to (ie. unbuffered?) If it does not, then the problem could be with the OS, not the libraries you are using. (cerr is tied to fd 2 (stderr) instead of fd 1 (stdout) and is supposed to be unbuffered, though both are based the same parent class (as far as I know, may be implementation dependant)).<br />
<br />
&quot;clog&quot; is supposed to be an unbuffered &quot;cerr&quot;.<br />
How do they do it? (tracking this doen might help)<br />

"clog" is supposed to be an unbuffered "cerr".

Thank you!

disable cout buffering

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
