import std.stdio;
auto f = File.tmpfile();
require 'tempfile'
file = Tempfile.new('foo')

A unique filename in tmpdir , e.g.: "/tmp/foo.24722.0"
#include <stdlib.h>
const char tmpl[] = "XXXXXX.tmp";
int fd = mkstemp(tmpl);

Template must contain six X characters that will be modified by mkstemp
New implementation...
