Hi.

The std.cstream.dout has a member function dout.flush.
But the std.stdio has not a function flush or a similar function.
Why? Don't you want to have it?
Give me the std.stdio.flush!

All the write functions in std.stdio (write, writeln, writef, writefln) flush automatically, so there is no need for a separate flush function.

Sorry, my mistake. It seems only writef and writefln flush automatically. :(

You don't need it.  Just import std.c.stdio and fflush(stdout).

I don't think so. If I run my code in the Eclipse console it doesn't flush automatically and I have to do fflush(stdout). I think it depends on the console implementation.

That's weird, and probably a bug somewhere. This is the definition of File.writeln() from the latest Phobos:

    void writeln(S...)(S args)
    {
        write(args, '\n');
        .fflush(p.handle);
    }

where p.handle is the FILE* pointer.

uhmm...
I think std.c.stdio is a port of the C language library,
std.stdio must has flush or fflush as the D language library.

IIRC writef only forces a flush on a newline.

It's not a port, it _is_ the std C library. std.stdio just adds functionality on top of what C provides.  That's what Phobos IO is, it's meant to be possible to use it interchangeably with C IO.

Tango IO is different, it uses the lowlevel OS APIs instead.
