redirecting standard error

[Rob Z]

I use popen in C++ to grab the standard output from Unix commands. Is
there a similarly simple and fast way to grab standard error as well?
I understand Python has different popen commands for different
streams, but don't know about C++.

Thanks

C++ doesn't have popen. It's your OS (UNIX) that does. And if Python
can do it, there is nothing to stop your C++ program from doing it too.
However, it's beyond the scope of this newsgroup, since it's OS-specific.
Try comp.os.<your_os>.programmer.

Or comp.unix.programmer.
