I could use extern(c) and Process Walking (Process32First,

means of D?
I don't think this is part of the standard library.
Here's a piece of code I wrote a while ago if that's useful:
```
pragma(lib, "Kernel32.lib");
/**
* Get a list of tuples for each currently running process,
containing name and id
* Returns:
* array of (name, id) tuples
*/
auto getProcessList() @system {
import core.sys.windows.tlhelp32: CreateToolhelp32Snapshot,
TH32CS_SNAPPROCESS,
Process32First, Process32Next, PROCESSENTRY32;
import core.sys.windows.windows: HANDLE, INVALID_HANDLE_VALUE,
CloseHandle;
import std.typecons: Tuple, tuple;
import std.string: fromStringz;
import std.conv: to;
HANDLE hProcessSnap;
PROCESSENTRY32 pe32;
hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
scope(exit) CloseHandle(hProcessSnap);
alias restype = Tuple!(string, "name", int, "id");
restype[] result = [];
if (hProcessSnap != INVALID_HANDLE_VALUE) {
pe32.dwSize = PROCESSENTRY32.sizeof;
for (auto notAtEnd = Process32First(hProcessSnap, );
notAtEnd;
notAtEnd = Process32Next(hProcessSnap, )
) {
string processName =
pe32.szExeFile[].ptr.fromStringz.to!string;
result ~= restype(processName, pe32.th32ProcessID);
}
}
return result;
}
```
