import std.stream;
import std.c.process;

void die(char[] fmt, ...){
std.stream.vprintf(fmt, _argptr);
exit(1);
}

Any help is much appreciated.

Nope, this doesn't work either. Sorry, but maybe its a lead.

Here is one that does work ...

<code>
import std.stdarg;
import std.stream;

BufferedFile f;

void die(char[] fmt, ...)
{
    va_list ap;
    ap = cast(va_list) &fmt;
    ap += fmt.sizeof;
    f.vprintf(fmt, ap);
  }

void main()
{
    f = new BufferedFile("c:\\temp\\test.txt", FileMode.OutNew);
    // NOTE **** The usage of 'C' style string format code '%.*s'
    die("Code: %d is '%.*s'\n", 12, "test value");
    f.close();
}

</code>

Not an answer but it would be nice if there was vwritef().
While looking through the docs I noticed writef() returns Stream when it  
should probably return OutputStream.

Yes, I was just thinking the same thing.

And I just slapped myself because a simpler solution is just ...

BufferedFile f;
void die(char[] fmt, ...)
{
    f.vprintf(fmt, _argptr);
}

note vprintf is not static so one must supply an instance of a stream as 
Derek's post suggests.
