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;

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.
