Is it possible to redirect stdout in a way that all following calls to
writeln etc just write to /dev/null or something similar?

Thanks!

And I need to restore them afterwards.

   stdout.open(outfilename, "wt");

If it's any form of unix, all you need to do is close(1). If you still
need the fd afterwards, you want to use dup() first so you can restore
them (with dup2()) later.

Thank you. After a first search, thought I need to use dup2, freopen etc.

If someone finds this thread, this is how to restore stdout:

Just store it in another variable like this.

auto original = stdout;
stdout.open(newdest, "wt");
//restore
stdout = original;
