Hi,
how can one redirect std::cerr into a file? Specifically, if I have an
ofstream object, is there something I can do to make "cerr << ..." calls
write into that particular ofstream object?
Thx,

I have answered this question loads of times in the past: you can
replace 'std::cerr's stream buffer. However, since 'std::cerr' is
possibly accessed after exiting 'main()', you probably need to
restore the original stream buffer or allocate your stream buffer
on the heap.
Specifically, if I have an ofstream object, is there something I can do to make "cerr << ..."
calls write into that particular ofstream object?
| std::ofstream out(...);
| std::streambuf orig = std::cerr.rdbuf (out.rdbuf());
| ... // use redirected cerr
| std::cerr.rdbuf (orig);

Hello,
Please bear with me, I am trying to learn C++. I am implementing some
error/debug functions which format a message and output it to a C++ stream.
I would like to design it using one low level function which accepts a
"generic C++ stream" as an argument (cerr, cout, ofstream, etc). I have
tried to make the parameter a const ostream&, but when I plug in cerr or
cout I get a compiler error. What am I doing wrong?

Here is what I use to redirect printed messages to a file:
std::ofstream file("logfile");
std::cout.rdbuf(file.rdbuf());
std::cout << "this message goes to a file" << std::endl;
Will the next message I print go to a file as well?
std::printf("does this message go to a file?");

Hello,
I am not entirely clear on the difference between cerr and clog. When it
is more appropriate to use one versus the other? I am coding a simple C++
application that will issue error and warning statements based on an
input, and I would like to know whether these should both go to cerr, or
whether clog for warnings is a more appropriate choice (or I suppose, just
cout)?
Thank-you,
