Detailed Description

Temporarily closes a file descriptor (typically, stdout/stderr).

Currently, this low-level implementation doesn't work with all C++ streams: on some systems C++ streams stay in a bad state afterwards and are silent forever. Standard IO streams (cin, cout, cerr) are checked and protected against this problem.
