• Colin Grogan (3/14) Oct 08 2013 I should have specified, this is std.stdio.File, not
• Daniel Davidson (14/34) Oct 08 2013 Is this helpful?

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!

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

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

Thanks.
