Hi all,
I want to create my own File in memory that I can pipe output 
to and read it in from another part of the program. I dont 
want to physically write data to disk, just store it in 
memory.

I've been trawling the documentation for the past while and 
the closest I can find is std.stdio.tmpfile(), however this 
always opens in "rb" and therefore isnt useful for me (I 
think!)

The reason I need to be able to make a File is because I want 
to send these IOstreams to std.processes spawnProcess().

Maybe I'm just looking in the wrong place?

Thanks in advance!

I should have specified, this is std.stdio.File, not
std.stream.File.

Is this helpful?

import std.stdio;
import std.process;

void main() {
  auto p = pipe();
  p.write("This is test\n");
  p.close();
  foreach( line; p.readEnd.byLine ) {
    writeln(line);
  }
}

Thanks
Dan

It does!
I see the Pipeing functionality in std.process now. Guess I 
should have looked harder :)

Thanks.
