Description

In Phobos I'd like a (portable across different operating systems) way to set the mode of stdout/stdin (to binary or text mode).


A not portable way to do in C on Windows is:

setmode(fileno(stdout), O_BINARY);


In Python a not portable way to do it is (works on Windows):

import os, msvcrt
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)


I think an almost portable way to do it is (this is a C99 version of freopen):

freopen(null, "wb", stdout);
