I've tested it out with DMD 2.053 on Windows XP.
import std.stdio;
import core.thread;
void main()
{
version(WIDE) // Will flush during write
wstring mystr = "Hello\n"w;
else // Will not flush
string mystr = "Hello\n";
write(mystr);
Thread.sleep( 70_000_000 ); // 7 sec
stdout.flush();
}
Also, there's nothing in the C standard that says, stdout must be buffered
this way or that way or even buffered at all. I believe you can safely
assume that stdout is line-buffered in Linux, though, but I'm not sure.
