digitalmars.D.learn - Get process

Looking at std.process I could not see a standard way of 
retrieving a process.

Is there any and if not are the functions available for just 
windows somehow?

I'm sure if there's no standard way I'd need to call the win api 
so if anyone could tell me which ones and/or the declarations if 
that's the case.

I really only need a windows solution.

I have adapted the answer on Stackoverflow [1] for D: // These Windows headers require DMD >= v2.070 import core.sys.windows.winnt : PROCESS_QUERY_INFORMATION, PROCESS_VM_READ; import core.sys.windows.winbase : OpenProcess, GetCurrentProcess; import core.sys.windows.psapi : GetProcessImageFileNameW, GetModuleFileNameEx; import std.stdio : writeln; void main() { // 1) Get a handle to the process // 1.1) Example - get current process: auto processHandle = GetCurrentProcess(); // 1.2) Example - get process with id 8036: // auto processHandle = OpenProcess( // PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, // FALSE, // 8036 /* This is the PID, you can find one from windows task manager */ // ); // 2) Allocate a buffer for the name wchar[2048] name; // 3.1) Call GetProcessImageFileNameW uint bytesWritten = GetProcessImageFileNameW(processHandle, name.ptr, name.length); // 3.2) or call or GetModuleFileNameEx //uint bytesWritten = GetModuleFileNameEx(processHandle, null, name.ptr, name.length); assert (bytesWritten > 0, "Error: GetProcessImageFileName() wrote zero bytes!"); writeln(name); } Please note that this is Windows only and you need to use DMD 2.070 [2] or newer. I'm not on Windows so I can't test it now, but this should be the basic idea.
