Fair enough. To me, even the lowest number fd guarantee is strange, so I though it was some POSIX weirdness (along with other weird behaviours for compatibility sake).
Anyway, even the { close(0);open(...); } is strange, as it doesn't take into account multithreading, so I wouldn't ever do anything like that, even in single threaded applications (I never know when a piece of code that seems trivial will be latter "copy/pasted" to a multithreaded application).

Fun with file descriptors Posted Jun 14, 2007 7:58 UTC (Thu) by slamb (guest, #1070) [Link] Avoiding code which is broken if copy'n'pasted into the wrong context is a hopeless job - the best you can do is state your code's assumptions, and whoever adds code (whether pasted or not) must take responsibility for it. Anyway, I can't really imagine when you'd ever want to replace stdin/stdout/stderr while multiple threads are going, so I don't know why someone would paste this there.
