In C:
fclose(stdout);
Now what? Now how can we print anything?
(I'm sure other languages allow programs to close stdout, but C has come
up in this thread before.)
There are a handful of real use cases for closing (or otherwise
changing) stdout; e.g., background/daemon processes, programs that
operate exclusively in a graphical environment.
