equivalent of Java's getErrorStream in C++ - need to capture standard error

I need to capture the error code put out by an executable which I run
from my program using

rc = system(command);

I get the stdout into rc. But how do I get to stderr ?
( command does cerr << errorcode; as part of its execution)

Can this be done without creating a file ?

Thanks in advance for your help.

There is no way to do that in C++.

Yes, by using OS-specific means, like opening a pipe instead of using
'system', etc. Off-topic here, ask in a newsgroup for your OS.
