any idea on how I'd convert this C# code to D?

==============================
public class Program
{

    [DllImport("kernel32.dll")]
        [return:MarshalAs(UnmanagedType.Bool)] static extern bool
        GetDiskFreeSpaceEx(string lpDirectoryName,
            out ulong lpFreeBytesAvailable,
            out ulong lpTotalNumberOfBytes,
            out ulong lpTotalNumberOfFreeBytes);

    static void Main()
    {
        string dir = "C:\\";

        ulong lpFreeBytesAvailable;
        ulong lpTotalNumberOfBytes;
        ulong lpTotalNumberOfFreeBytes;

        GetDiskFreeSpaceEx(dir, out lpFreeBytesAvailable, out lpTotalNumberOfBytes, out lpTotalNumberOfFreeBytes);

        Console.WriteLine(lpFreeBytesAvailable");
        Console.WriteLine(lpTotalNumberOfBytes");
        Console.WriteLine(lpFreeBytesAvailable");

    }
}

=================================

import core.sys.windows.winbase : GetDiskFreeSpaceEx;

Use wstring's and .ptr them and everything should work.

Hi Rikki,

   Wouldn't this be easy to use with std.process: execute package and calling wmic.exe, the only problem is i am not sure hot to get the out put without the headings(Caption  FreeSpace,Size) any help on same is much appreciated.

import std.process: execute;
import std.stdio : writeln;

void main () {
version(Windows) {
auto result = execute(["wmic.exe", "logicaldisk", "get", "size,freespace,caption"]);
writeln(result.output);
}
}
Output :
Caption  FreeSpace    Size
C:       19702837248  180043665408
H:       85580382208  824633720832

Don't call external processes when you can call a function. Running another process is overhead and not reliable.

writeln(result.output[38..$]);
